You can go Japanese a bit cheaper. Lee Valley carries one for $50US http://www.leevalley.com/wood/page.a...072,43071&ap=1 and this guy on e-bay has the same price http://cgi.ebay.com/SHARPENING-WATER...QQcmdZViewItem I can't make any guarantees about that particular seller. Lee Valley also has waterstones in the 1000 grit range in case you are planning on doing lots of blades.
Tony Miller has a very good design for a bench hone for about $15. Check it out on www.thewellshavedgentleman.com
