What cranks do you intend to run? If you're running 3pc tubular bmx cranks, just get an American bb set that accepts whatever spindle you intend to run (most common is 19mm.)
If you're running old-school 3pc cranks w/ a spider, like something from the early 80s or prior, you can run the complete adaptor with the 127 or 130mm spindle, such as this YST:
These are popular with folks here on RRB b/c they're cheap (as in, the bb is cheap meaning "affordable", but also as in the RRB members are cheap meaning "stingy") but they will mess up your chainline with the vast majority of 3 piece square taper cranks.
If you wanna run basically any cranks that go into english threaded aka bsa aka bsc aka "normal" aka euro bb shells, get the threaded adaptor like this:
This presses into your bb shell, and then you tighten the 3 bolts down, and then you can put any 1.37"x24tpi bb into your frame to suit whatever cranks you wanna run... and it'll help you achieve your desired chainline, too.
127mm complete adaptor available here:

If you're getting a real bmx (ie, not a bmx race crank), I'd suggest buying the appropriate bb from the same source as you get the crank. (You'll need the American bb.)
Please remember: you'll need different pedals, too. 9/16" spindle. The 1/2" pedals on your OPC won't fit.
In closing, for a Felt cruiser, the OPC is arguably the best choice anyway.
