amp for atlas 12's

Just curious what a decent amp for a pair of Atlas 12's would be, they'll each be in a 1.5 ft^3 sealed enclosures. Ascendant recommends about 250-300 watts each into 4ohms, but I'm not really keen on current car audio and have no clue where to start looking for an amp. Only reason I got these is because of the new sale... Anyways I'd like to keep the price below 250 bucks, but feel free to mention any good amp, cuz if its worth it I'll pay for it.
