BKent,
I did this same poll back around Christmas time last year. We had a PS1, and hub just got back from a 3 month stint in Saudi Arabia, and had some extra cash coming from it.
Nearly everyone agreed the PS2 is the best bet. I said NEARLY everyone. That's because you are going to get differing opinions based on what everyone else likes, which is normal, but you are in the same boat as we were. You have PS1 games you still like to play. It is that reason, plus the fact that Playstation has more kiddie games for our sons than the others. We bought our Playstation almost a year ago and we love it. No regrets.
