I bought my husband a Tivo Series 1 SVR-2000 for Christmas on Ebay but it did not come with a remote?

I thought I would just buy a compatible one, but I am now learning that they are very hard to come by. I saw a couple on Ebay but they are a little more than I wanted to spend. I read that the Logitech / Harmony 659 Universal Remote works with it. Is this true? I am not that familiar with electronics and don't want to find out, on Christmas, that it doesn't work. Any advice?
