They are $79.95 if you buy two, and $89.95 for one from SOG. But you have to have an FFL (01 or 03) and you pay shipping, so I'd say $125 is a fair price.
Dennis Kroh has them for $85.00 and he has a good rep, although I have never bought from him:

Some folks say you can use 32 long in them, I don't know as I don't have one.
This site is devoted to them:
