best bypass for trailblazer

I've looked through many post but can't really find the answer. What do you guys think is the best bypass for this car. I'm only doing R/S and keyless. Also which would work best if doing alarm to.;

Trilogix GM-DLBP is the best for the money. It does lock, unlock, driver's-priority unlock, factory alarm arm/disarm, domelight turnon, perimeter lighting turnon, panic, and bypasses the Passlock II for remote start. If you were doing an alarm, it has a door trigger output too. If you want to spend a little more money, the Trilogix XK-01 does all of the above, plus window rollup, and also automatically turns on the defroster and heated seats at 32*F or below. If you choose the XK-01, be cafeful who you buy from. That module can be shipped with various firmwares......Hyundai, Toyota, GM, etcetera. Be sure the seller will flash the module with the proper firmware for your Trailblazer.

For my keyless and R/S i should go with Trilogix GMDL BP
