My TV gave up the ghost last night. Just sits there making a mysterious beeping noise. I don't particularly want to put money into getting it repaired.

I'm a little behind on TV technology, so maybe you guys can help me a bit. I want my new set to be HD ready but have some questions about it:

If I get one with an HD tuner, can I still tune standard channels?
Which HD standard is the one I want (you know...the good one)?
What are the best brands? Are Sony tubes still the best?

Any suggestions on a TV? Criteria: under $1000, 32-37", tube or flat is fine.
