the chameleon w/ solderless adaptor (if you have av1.5 xbox, you have to solder 2 connections (it is still easy)) is a good one. the xecutor 2.3 lite plus is also solderless and easy to install, but I am going on what others have said as I have never installed one myself...this chip has a few more features than the chameleon including an easy on/off switch for your modchip (so you can play on xboxlive w/o getting banned) --cheers
I replaced my xecutor 2.3 LITE+ with the new xenium. I like the xecutor but I did'nt want the external switches and the xenium has it's own OS and all programing and bios setup is done via a buttons on the controller. Either one is ok but I prefer the xenium.
