Clearly you've done a lot of research, and I'm sure you've probably already heard this, but it bears repeating. The best thing you can do is make sure your rig is in good running condition before going down the tuning path.. too many people try to and sometimes successfully use the tuner to mask issues they're having with their engine and that's not a good thing..just my .02 cents.
Also, FWIW, I run my tuning software off of my $100 ASUS netbook. Haven't had any problems at all.
