The 2.5 Gal are much tougher to come by than the 5 Gal. I've been watching CL for months and nothing...
I just bought a few 5 Gal corneys from homebrewing.org and I'm happy with them. The used corneys came pressurized and are in decent condition...$59 each, the best price I could find. The new corneys are beautiful and at $75, also the best price around. I was super happy with the service and turnaround with AIH...placed the order on Saturday and had a call first thing Monday morning confirming my shipping address (because it was different than my billing). Received the package before noon Tuesday (with standard shipping). I'll definitely order from them again.
