I got my U-360 from UQG optics, do be aware though that they pass significant amounts of IR too, which digital cameras are more sensitive to. (I think even those with strong hot mirrors).
In addition many lenses will themselves absorb significant UV, uncoated lenses with minimal glass are your best bet unless you can afford (& find) one of the ultra rare quartz lenses Pentax made.
Good luck!
BTW Klaus (AKA kds315) is now a member & is very much an expert in UV photography. His website is a great source of information on it.
