Yeah, I didn't realize RCA was making HDTVs either. I just googled HDMI, and it was the first >37" TV that showed up in the little Google shopping box. I don't know for a fact that the connectors I pointed out are RCA, but I think it's a safe bet.
I also know for a fact that the Toshiba 40RV52R (obsolete) has RCA out, so it seems reasonable that RCA out is not a white whale. If I were you I'd ask a salesperson at Best Buy or such, they probably have a better idea than most people.
