Thanks for the input. Looking at the Thumbler, it seems more heavy duty than the one in the basement but I might give it a shot anyway. I'd rather put a little extra into a digital scale at this point. If not, the Cabels's link given looks like a good entry point (I should have thought of that, I have a Cabela's less than a half hours drive). And the colander idea, pure genius, maybe I'll even try the wife's salad spinner.
In general, I see this is going to be a good source of info as I get started. I plan to order a 550B from here soon. Doesn't look like there's a good market for used equipment at much of a savings. Especially considering free shipping and no sales tax. Given a little time, I'm sure I'll be posting a pic of my reloading room.
