Smoke,
I cant vouch for how they shoot as I have never owned one, but I saw a used one for sale recently at a flea market here in Indiana and the asking price was $225, it looked like new on the outside, cant speak for the condition of the bore though. Used sidelocks in good to excelent condition average $200-250 here. If they look rough or have rusty bores you can pick one up for $100. Hope that helps.
