Lots of places are reputable. Check out the stores mentioned on the web page that I posted in your other thread. Also, OneCall is particularly good. So far as ebay is concerned, look for mfgr's warranty, an actual address for the store or seller, shipping options appropriate for a delicate instrument, credit-card capability, a stated return policy, and a favorable feedback rating. Prices on the web and ebay are generally better than what you'll find at Best Buy et al. for flat panels.
