What's it worth?

I got salad shooters, they don't have much tire left on them. what are they worth in Canadian money?

There's a guy selling a set (wheels only) on ebay right now, here (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7970322714&category=43956)

His "buy it now" price is $160USD, about 200 loonies.

$75?
