Need 3-4 Psion Series 5 handhelds for VCF

I'm in need of 3-4 Psion Series 5 for the upcoming VCF. They're to be used as portable terminals for the judges to use in scoring exhibits. I'm trying to source them for under US$50 each. eBay has been OK and I've gotten a couple from there already but most keep going for over $50 each and my budget won't allow me to go higher. Does anyone have any for sale, or know of where I can get some for under US$50? I don't care if they are ugly or if certain non-critical parts are broken (i.e. broken doors, latches, etc.) As long as it powers up, the screen works, and the CF slot works then I'll be happy (of course I'll want to pay less for such units).
