I have had good use out of TCL with Roku built in as a good value purchase.
Probably not the best quality screen for those picky about such, but it works well and the Roku system beats any other smartTV for ease of use (without you needing to log on through the manufacturers company before you can access Hulu, Prime, and Netflix!
Check pricing with WalMart Online as well. Costco may beat them, but Walmart
online is often the best selection/price for a tv. I always wonder that they are kind of screwing over people who buy in-store!
