You can get the rams for $40 each shipped on EBAY.
Might be worth throwing a low ball offer at the guy, because they don't show up often I suspect you aren't going to see them for a lot off of retail.
Rams are cheap but by then I'm practically at the same price as a new one with everything included, even casters. I may hit him low and see what he says. Worst he can do is say no.
