New roller cam...

Hey guys, i got my 440 through break in this weekend and ended up with a lifter going concave on the bottom so im guessing it's as good as a paper weight now. i did all the break in procedures as listed on comp cams website but that's what i get for going with a flat tappet. i was wondering if anyone had any good opinions on a good roller cam for my setup. ive got a 10.0:1 440 with stock ported heads and a 2500 stall converter. with 3.91 gears. the cheaper the kit the better because im only 18 and not full of money. any opinions appreciated.
