I've seen a few people with them. Price is high compared to group buys, and ROI (Return on Investment) is becoming difficult!
No, the price is very low compared to the USB block erupter group buys. ROI would be much easier with BFL units.
The actual problem is the order backlog. While the units are much faster and cheaper per Ghps than the block erupters, if you order today it will take a while before you receive the product. That's how ASICminer can charge very high prices for very slow units - the competition just isn't able to deliver enough units.
