Sounds to me like you want a few more features than a programmer, personally i wouldn't waste my money on a hand held OR a mail order tune.
Buy yourself the HP tuners or EFI-live cable, and visit their forums accordingly for tuning advice. Premade tunes similar to ones from the handheld devices will be available for you to upload into your car. Also the option for more custom tunes stands, as you learn more about tuning.
