Yup, the original Stacker (STC-T01) is the only one at a reasonable price. SVC.com has the blue one at $100. after rebate, but the shipping's a killer unless you can go pick it up or are relatively nearby so maybe you could talk them into using Parcel Post - I just sent 22 pounds of printer to Ohio from central NY for $13.23 exclusive of insurance. Zipzoomfly.com has had them at decent prices too - might come out ahead at the bottom line. ZZF definitely has the best bottom line on the blue one - even after rebate unless you can pick-up or ship Parcel Post.
. Rack style cases generally have space for compact redundant PSUs - not two ATX PSUs. The Stacker has two full-sized ATX PSU bays.
