VCR-to-DVD advice sought

I have a bunch of videotapes that I'd like to convert to DVD - things like the Shining Time Station Christmas special and the Harris/Dietrich pimping tape. I don't think my computer has the horsepower to do it digitally, so I'm thinking about getting one of those machines that's basically a videotape player and a DVD burner together. (I think Go-Video makes one.)

Has anyone used any of these? Can you recommend a good one? All input gratefully received!
