I gotta weigh in in favor of the Rossi 92 as well, tis what I would get if I had a pack of young'uns comming up. You can buy two or three of them for the price of a 73 and the will run darn near as fast. The 16" version will fit 10 38's and with a cut down stock (save the cut off piece to screw back on as they grow) they make a pretty nice kids gun. If you go the Rossi route look up Steve's Guns
For a very good video on DIY slick up, very informative as well. Steve is a great guy to work with and sure knows his Ross's!
Good luck with yer home growed posse!
