Here's a CL listing I thought was interesting:
http://sfbay.craigslist.org/eby/for/942900339.html
Brand new in the box 22 1/2 in Weber BBQ from the 1970's. Series 70000. Very unusual blue color for your patio. Never used. contains all parts, unassembled.
$195 seems steep to me right now, but if I had the cash and was in a collectiing mood, I might go for it.
