They are common and were made in two variations a clip fed version and a tube magazine fed version. They are common and not hard to find I have actually owned several of each type over the past few years. Pricing is in the $100-$225 range I paid $250 for one but it had the original box and papers with it(Looked new in the box). Clips are easy to find as Marlin used the same basic frame for several versions of semi-automatic .22 caliber rifles. Good Luck looking for one.
