OP, If you don't want to spend more than $1k, go OME. If you want or are willing to spend more than $1k on suspension, check out OW and ICON. In the end your 4Runner will ride WAY better than stock either way.
Each one of us will persuade you to go the route we went or are planning, I have OW, I'm gonna push you towards the OW kit, SandCrawler has OME components, he's gonna persuade you towards the OME kits, SeattleMike will persuade you towards the OW kit as well. Also, Harper and Mr.Grimm and a few others will persuade you to go with the ICON kit cause that's what they are running. In the end, whichever one of "these" methods you choose will provide a great ride.
Depending on how much "off-roading" is in your future, having re-buildable shocks might in the end save you some money. Not so much today but in the years to come.
Good Luck!!
edit: one of the reasons I never really looked into OME was that their shocks are Twin-Tube and when your off road working the shocks, they cannot cool as quickly and easily as a mono-tube style shock and will start to fade. The Toytec kit that uses the Bilstein 5100's, those shocks are mono-tube and as far as I know will hold up better in offroad conditions. Of Course Coilovers are the best for off road conditions. 2.5" diameter, and mono-tube style design offers plenty of fluid and cooling surface. I hope this info is accurate, if not someone correct me. It's just what I remember reading while doing research in the past.
