I think you should take a look at the video I posted and read the video description. Call the company I linked and they will get you a set of injectors for much much more of a affordable price than the crazy options you posted.

I replaced injectors 1 3 and 5 last week. I had been dreading this job for a long time but it really wasn't all that bad. I got the upper plenum off, cleaned it, and replaced the gasket, but I was feeling lazy and didn't remove the lower to get access to injectors 2 4 and 6. It's probably possible to replace 1 3 5 without evev removing the upper plenum - you definitely don't need to remove the fuel rod, I just kind of twisted it up and rocked the injectors out. Took maybe 4 hours start to finish with a lot of breaks and a detour to remove and replace a stripped screw on my maf sensor. Could definitely do the job in about two hours if I did it again.

I replaced all mine when injector 2 took a dump on me and ohmed st over 23 ohms at the internal coil.
I used OEM rebuilds from MotorWest and replaced all 6 that were flow matched. I replaced valve cover gaskets while in there and painted valve covers and degreased and pressure washed the manifolds and replaced vacuum lines.

FWIW I did the even injectors on my 99 v6 5 years ago w/ Beck Arnley's from Advance Auto. 5 years, and 60K miles later I have had no issues. Looking back I wish I had done them all, but it wasn't in the budget at the time. I needed to get the car up and running ASAP and those were the only ones in stock (tried dealership as well). Using a variety of 20% off online purchase coupons I got them at a decent price.
I still don't understand why the coupons are only good online. Can't tell you the number of times I've gone in for a part, had them pull it from the back, then gone online to purchase and use coupon, so they could hand it over to me.

This spring I had an issue with #6 injector on my 99 (228K miles). Ran fine most of the time, but if the engine got really warmed up, it would start intermittently missing, progressing to a fulltime miss and a #6 misfire code. When the engine cooled back down, it would run on all6 again with no signs of trouble.
So I got it nice and hot and missing, and tried to troubleshoot it by moving wires and coil packs around. And the miss stayed firm on #6. It was clearly not a mechanical (compression) issue because of the on-off way it operated. So... injector.
My mistake? Getting on eBay and buying a set of 'BRAND NEW GENUINE OEM 100% GENUINE INJECTORS' for about $250. Yes, there's absolutely no way you're going to get brand new 'real' OEM injectors for $250. Dumb me. Got them in, they were in some shady foil packets (I forget the wording on them, but it didn't inspire confidence. The injectors themselves? Really good fakes. I looked at the original injecors and those side by side up close, and I really couldn't see anything wrong with them. Other than a skinny looking set of red o-rings. So I put them in.
And...it was hard to start. Like 10 seconds of cranking. Hot and cold. Maybe a little better in a 'warm' start. Clearly, one or more of them was leaking down while sitting. Told the seller this, they said they needed to 'break in' and to drive it for 50 - 100 miles and see if it improved. I did that, if anything it got worse. Ah well, I took them out and returned them, at least the seller gave me a 100% refund (in exchange for not leaving feedback).
And I went to a junkyard and got a set of used injectors from a wrecked '00 4Runner. When I pulled them off the fuel rail, fuel sprayed out under pressure. Lol, no leaks on this set - they'd been holding pressure for at least a month or more. Stuck them in, it runs perfectly, cost only about $50 for the set. I figure a junkyard set with 200K on them are probably a better idea than a 'new' set of eBay knockoffs.

I bought these

same ones I pulled out, so someone had replaced them before I bought the car back in 2011. I put 125k on it before #5 died. the others were still running fine.

Hey have you tried cleaning the MAF sensor, as my 1999 was runing pretty bad, and had no power. so i cleaned the sensor and it is way better. also look at your pcv valve as that is the easiest fix.
