someone convince me to unlock and flash a rom

[TP1085]

i've been reading these forums for months now, and i just finally got my tp2 about a week ago, and its so much better than the original. however, as with the original, i'm nervous to unlock it and unsure how much improvement i'll see. i know i want to try flashing i'm just nervous that something would randomly go wrong and screw up my phone - paranoid, i know. anyway, just ranting i guess and looking for someone to convince me to make the leap. if i do, i think it would be to mighty mikes 2.1 rom, it sounds like it is the most stable, which im looking for, despite really liking the looks and especially the people tab of 2.5.
