The Sony KV-36XBR450 Wega is $1873.95 @ Crazie Eddies. I also see other models at my local Best Buy which seem to be a few $ more, like the model KV-36HS20, but what is the difference? Is the later the HD version? It appears that everyone goes for the XBR450? Please post your thoughts on these models and any deals on these too...Thanks.
