i've heard a pretty reliable rumor something really nice might be coming out soon in the price range of an obdlink. if you're not in a huge rush and like to gamble maybe wait and see if that happens. the guy working on it is so stubborn that its unlikely it wont happen, just not sure of timing.
That's a great summary of where we're at right now.

I've got a prototype of the rumored interface and it works great. I'm sure it's going to be the best option when it becomes available. I don't think there's an ETA for that, though. Last I heard, the guys behind it were still refining the design and working out how to get them produced in volume.

If you have a car you want to tune now, I'd say get the ObdLink and go for it. It works fine, you'll just get faster flashes if you buy the new interface later.

I'm not sure about the Tactrix, but if you have one, give it a try. They definitely support the J2534 standard, so the app should be able to talk to the device, but I don't know whether they support the VPW standard, so the device may or may not be able to talk to the PCM. Easy to test though - if "read properties" works, try a test write, and if that goes smoothly, you're good. I've been meaning to try it myself, but I don't know where mine is.
