When we took delivery of our 271BH we had our dealer mount the TV for us. We didn't feel comfortable doing it ourselves so we went to a local Best Buy and bought a Dynex 24" LCD/DVD combo TV. Due to the LCD (instead of LED) and DVD combo it's not the lightest slim-line TV. Here is where they installed it. Hope this helps.
Funny you post this, though! A local Best Buy is going out of business so we actually went out today and purchased a 22" LED TV on sale for $129 and a cheap mount for it. We're planning on installing it ourselves in the bedroom. My plan was to use a stud finder and mount it on a stud. I'd love to hear from any owners who installed their own.
