RE: Need experienced opinions here...
$300 doesn't scratch very deep into the catalog these days. Hoyt, Onieda, Mathews and Bowtech don't have anything priced less than $300. Look in the Cabelas or BassPro catalog. That's where you'll see most of the bows left on the market that are in your price range. Or check out some of the on-line dealers. Then head off down to the local shop and see if they carry them. If so, you're in business.
Honestly, most 'budget bows' are plenty decent. They will shoot an arrow just as accurately as the top dollar stuff. They might not shoot that arrow quite as fast; they might have a bit more vibration; they might be a little more challenging to shoot a 300/60X indoor score with; but they'll get the job done.
Prices they're asking for bows these days are outrageous. But... what isn't priced outrageous any more.
