I love garage sales ....that's where I find a lot of models some complete and some not. The incomplete ones are fun because they usually a dollar or two and makes the imagination go wild :)
Rani models, model trains, fishing tackle, poles, and paint. and the normal TOOLS anything thats usable in half decent shape! Ohh and storage items, for tackle, or model parts, and even cabinets, for such from old sewing rooms work great too!
