Seems like a reasonable deal, especially in today's market. An adjustable stock was the best thing I ever did for my AK (followed closely by the Hogue grip like the one you pictured).
The mag release looks more complex than mine, maybe that's a California thing? Also, I'm surprised he didn't have the safety changed out or modified to provide a hold-back slot for the bolt handle as long as it was being worked on by a smith.
