You own a $3,000 TV and a $1,500 receiver, yet you only want to spend $300 for a DVD player????  Interesting.
You can get a Blu-ray player for $500.  Seeing as how there is only ONE movie studio that solely supports HD-DVD, I think Blu-ray is the safer bet.  If you're waiting for the format war to end, I think you're going to be waiting for at least another year or so.  But I can understand not wanting to feel like you wasted your money too. 
Good luck.
