I'd be wary of buying shoes by mail order, especially from ebay. You don't want to find that the shoes don't fit after trying them out on the bike and being unable to return them.
I don't think you'll struggle to find shoes that fit. Most of the major brands do larger sizes, i.e. Sidi, Northwave, Mavic, Specialized. Shop around at this time of year, as shops sell off 2009 stock, and you'll probably find a good deal.
Are the shoes going to be used exclusively on the track?
