If they have a QBP catalog (and any shop that doesn't is a rarity), they can order you a Surly Cassette cog. Surly's go as high as 22t. If you are willing to go online, endless cogs (from
www.endlessbikes.com) go up to 25t, and have a stellar reputation. Each will probably run you about $30, but considering the quality of the cogs over your Shimano DX cogs, it's worth it.
If you decide that you want to drop coin on something that will last forever, Boone Ti makes Titanium cogs to order. Any size. Also, I think Spicer sells Ti cogs as well.
