Nice little guns and very handy to carry in the woods. I've had one for many years. disassembly/reassembly is not for the faint of heart, but on the other hand they're quite reliable and require little serious work. They're also a lot of fun.
If I'm shooting from a bench though, I generally like a full-sized, heavier rifle. I've never (personal opinion!) understood why someone would put a scope on a quick little rifle like the BL-22. It's perfect with open sights. If someone wants to do serious .22 shooting with a scope, I'd use a different rifle. $400 seems really fair... take off the scope and have a blast! I'd even put a peep sight on there before I'd ruin the lines (and overall size) with a scope.
