Want A Programmer Which One

After reading all the posts what is the best programmer to buy that gives you the best mods and performance that leaves no codes and will not void your warranty?

What is the going price for this type of unit. Please send PM if you can't post

Thanks in advance.

HPPIII is said to be the easiest to install and use, Superchips have had the most problems, and Predator is the most expensive, but does offer an on-the-run diagnostic feature. I would say that it comes down to price, because all of the programmers have relatively the same functions.

what can I get one for and is there a group buy?
