My only idea for getting stormies and clones is to get those action figgies they sell in like Target, fix the limbs in place and fill the screw holes, add some detail, and then pose them on a base. Havn't tried it yet, but I'm thinking of doing a dio of the Republic Commandos advancing through a droid factory or among wookies. BTW, Starwarsmodels.com is an awesome site!
Hasn't been updated in a while but gives a fantastic overview of both garage kits and the AMT/MPC stuff.
