Seems like they would get one to me for $41 delivered with "economy ground" shipping, Amazon is about $50. I've never used Allied, so you're right, I'd probably go with Amazon myself for trust factor personally. Makes me glad I jumped on a few Model B's when SparkFun was blowing them out for $25!
I hope the CHIP computer ends up working out, $9 compared to $40-$50 plus $10-15 more for wifi and SD Card is a big difference. That would shave at least $40-$50 off the cost of a HM. I don't find the size of the rPi an issue, I'm not a fan of miniaturizing things until they are difficult to use, I think the HM is just about the right size as is.... but a big reduction in hardware cost would be nice!
