This is the vendor, but she doesn't have any at present: http://www.ebay.com/sch/lenalosku/m.html However, this guy has them (DP-5V) listed, also sells Nixies, GM tubes, Xray tubes, capacitors, and more. Found him (Denis) most helpful: http://www.sovtube.com/en/ If there are things listed in bulk lots but not singly, just ask. SBM20s are the low-range tube used in the DP5-V, pretty good work-horses they are. If you want a bit more sensitivity and don't mind extra physical size, The SI22G is VERY sensitive. Not sure how this list handles attachments (if at all) but I've just taken a photo of an SBM-21 (in plastic bag,) SBM20 (middle,) SI22G (huge!) for comparison. Have plans to make a Nixie display benchtop counter, using as close as possible to the DP5-V tube-regulated power supply as I can. (Will still cheat and use a microcontroller, though!)
