Jesse, you might want to look at a Gryphon...its the one i ordered two weeks ago...still waiting for it...but I have heard nothing but good things about them....
I bought my Diablo for under $200 on ebay and it was less than 6 months old. Free software upgrades for life from Diablo whether you bought it brand new or not, too. Just a thought if you don't have to have the dash pod.
$399....you can order custom tunes as well. i believe the dash pod is included in that price as well.
Well I ordered mine just for economy....I ordered the performance and the tow custom tunes in 87 octane...I don't plan on racing my truck but i do haul stuff and would like some better MPGs.....thats why I ordered mine so I am in the same boat as you...but I wanted to make sure I got a decent programmer and everyone told me Gryphon (especially since so many people send their Edge's off to be converted.) not a single complaint.
Good luck. I emailed a bunch of them too back when I was looking and never heard back from 90% of them. Those programmers are a hot enough item that they usually sell themselves pretty quickly. I got lucky and sniped my Predator as soon as the guy listed it for way less than what they were going for.
