Touchscreen Manufactures

I need a little help here. Currently we have over 30 21″ crt touchscreen from ELO on our manufacturing floor. We are now expanding and we need more of these 21″ crt touchscreens. The problem is that ELO’s interface cards are only ISA and as most of you know new Gateway PC’s don’t come with ISA slots anymore. So what I’m wanting is any information that can get me around this problem. Perferible a touchscreen with an PCI card. I need this soon so any ideas would be great!!!
