Great TV, no issues at all. Excellent condition. I'm moving soon, so I'm trying to get rid of it.

I've been using these Altec Lansing speakers that I had from way back - it's a pretty good setup. I'll throw the speakers in for an extra 20 bucks - I don't think you can buy these anymore, but they still sound great.
