Which DVD recorder for TV recording?

I really want to get a DVD recorder. This will be mostly for recording from the built-in TV tuner but I may also run computer output to it and record that. I don’t have any home video tapes to transfer. Which would be a good bet? I am looking at either a LiteOn LVW-1107, LiteOn 5116GHC or Panasonic DMR-ES15S. I want to buy locally so if it doesn’t work I can return it easily.
