cheap vs expensive flexplate

discussion welcome. buying either a 8 buck oe flexplate, or a nice b&m for my 360

i also know that it needs to be balanced, so im guessing that because its a oe flexplate for a 360, it will be balanced. 360 came out of a 87 dodge pickup
on a budget, and the $8 is lookin pretty neat. but can it hold a buncha hp?
