so far the only one that fits my budget and i feel 'safe' buying is the innovate motorsports lm1... http://www.innovatemotorsports.com/lm1.php
it was recomended to be by someone on this forum aswell.
its a big ugly box, but it seems to be nice quality and has 44mins of internal datalogging of up to 5 analog devices (tps, rpm, etc) and one analog output for a nice dash mounted guage if need be. I also dont have a lap top right now so the internal data logging is really cool.
all the other ones from what i can tell are designed more for looks then functionability, which i dont know if thats a good thing? I've looked at the plx, techedge, and aem, needless to say i wasn't impressed
i have a budget limit of about 650 canadian inculding shipping+taxes, although i'd like to spend the least possible
