I just placed my order for a 537H with J&R last night. They called this morning to verify the order and said it'll be released today for shipping. I paid a little extra for the 2 day shipping, so I hope it'll arrive tomorrow, though I don't really expect that. More like Monday or Tuesday (depending on when it actually goes out).
I actually bought this to replace my old Sony 32" tv which I bought in '99, and finally died on me 2 days ago. So I didn't get much time to research, however based on the great reviews of the previous Olevia models, and the positive comments here at AVS, I made up my mind. Thanks!
