I'd give a call to some of the auto recyclers in the area and see what they have. You may also be able to call up one of your local tire stores and see if they have any stock rims layin' around from a customer upgrade.

There are 2 exact rims for sale on eBay:
CHEVY BLAZER S10 S15 SONOMA JIMMY 15 OEM WHEEL RIM 5063 - $105 + calculate shipping (http://cgi.ebay.com/ebaymotors/CHEVY-BLAZER-S10-S15-SONOMA-JIMMY-15-OEM-WHEEL-RIM-5063_W0QQitemZ8061260002QQcategoryZ43955QQrdZ1QQcm dZViewItem)
AND
WHEEL OEM CHEVY 15 X7 GM SONOMA YUKON CANYON BLAZER RIM - $95 + $40 s&h (http://cgi.ebay.com/ebaymotors/WHEEL-OEM-CHEVY-15-X7-GM-SONOMA-YUKON-CANYON-BLAZER-RIM_W0QQitemZ8061321861QQcategoryZ43955QQrdZ1QQcmd ZViewItem)

I just copied the descriptions even though they are obviously wrong. Both rims are the exact same as the one pictured.

Good luck.

*EDIT* - there are a few more if you use the search term "s10 rim 15".
