Well, I had a backwards compatible PS3 for about a month until I finally got fed up with a unique crashing problem it had. I now have a newer, 300 GB model and it works pretty slick. I cannot really comment on the usefulness of the backwards compatibility because I never tried it out, but I heard it does not work for all games or, at least, work very well. You might want to consider buying a new PS3 if the price is similar to the used one and just get another used PS2. Maybe check to see if the games you are interested in playing work with the backwards compatible PS3 you are looking at to help you decide.
