I think the wsms are really worth the investment if you can't find one used. Mine will be here LONG after my drums rust out, and it's sure easier to clean or set up. Of course, with the porcelain coating, it's not like I'm worried about rust or burn out. We got mine right before Christmas for $269 w/ free shipping, and a Weber spatula and pair of tongs. I think similiar deals show up on Amazon, etc.
I don't think they sell near as many Webers down here in the south as they do up north. Like I said, you can't even find one in a store down here. However, you might come across one on the CL since you're checking in such a large metro area. Good luck!
