heres a few links you could also look into. http://www.giantscreamingrobotmonkeys.com/monkeyjam/ and http://www.animateclay.com/download.htm im not sure if they are still supported (ive only used the second one, sma, on an old 98 in '00 and it was crashy-crashy) but if your into stopmo, it might worth trying out as it would help develop some useful stopmo skills and the onion skinning features are definitely worth using. and they are both free! gota love that. hope it/they work out for you, no doubt you might find more if you scan those pages looking for links or referals. good luck!
