Bought one finished for my son 7 years ago for 200. It was the only thing in my price range for a lefty.
It's a surprisingly good shooting gun. slow twist, ball shooter.
It should be an easy kit(beginner type), I did dis-assemble the lock and polish/tune the parts for a smoother action and I did re-cup the hammer as we had a little trouble with fired caps sticking in the hammer. ( that's a bad thing, as copper shards tend to sting a bit and can leave a nasty little cut). I did make sure we went through a proper break in period for load development and the learning curve.
It's a good gun, he's 15 now, and he uses the same gun at rendezvous with his young eye's and makes some of the old pro's re-learn humility.( that's a good thing).
Good luck, I think it's a good choice for the money. Just don't expect, "off the shelf" accuracy being the same as spending 500 or more
