Wheel spacers can be bought for around $200 new, give or take depending on the manufacturer. All-pro and SpiderTrax are the most popular ones. Some people are fine running them, some people will not. Personally, I wouldn't mind running them, I just wanted new wheels. Also, some tire shops have a policy of not working on a vehicle with spacers...don't know why, they just won't.
Wheels can set you back anywhere from $200 or so up to around $800+. Mine were around $450 shipped. So for a couple hundred bucks more, I got new wheels (which looked way better than the triple spoke stockers) and I have not rubbed one bit. Full lock and off-road over rocks and trees its all been clear. I didn't even need to pound in the pinch weld, and I gained more clearance from the UCA.
