I know you didn't ask me, but I've used www.witchhunter.com many many many times over the past few years with no issue at all. It's a shame they are almost at RC Engineering prices now (which is another good option as well), as they used to be like $12 each to get done, including new o-rings, isolators, etc. Fast turn around, print outs are included and easy to read/understand, injectors are cleaned internally and externally, new o-rings, yada yada. I know they used to not charge you for injectors that are bad, but I don't know if that's the case still or not (I'd imagine it is).
No affiliation at all of course.
LOL I was going to recommend witchhunter also. I think it adds up to ~$100 with shipping both ways...
I've also bought from tlfperformanceparts on the fleabay. They refurb injectors and sell there. They come with flow sheet. I am running a set in my car from them right now and they seem good. Looks like ~110 shipped from them for you.
I've used Injector Rehab and Witch Hunter, I have no preference. Witch Hunter also let me know that I sent them crap injectors once and took no money from me.

Somewhat local (OKC). Great servive, nice reports/printouts, compettive pricing. Would use again.
