Where to find 10k mono stepped attenuators?

I am looking for a pair of 10k mono stepped attenuators for a subwoofer crossover that I am building. In the past I have bought them from Valab on ebay, but I can't find that seller presently. I looked at the DACT offerings, but they are way too expensive for this project. Linear taper preferably, but log is workable. Where can I find them?
 
I think you'll like the SMT resistor control, very good quality, and it's available in knurled or flatted shaft.
Too bad they don't make a linear taper version. The bushing and shaft are metric, of course.
Note the shipping for two controls is only $1 more than for one.

The rotary switch on the mono control is not the best, but will do ok for semi-permanent settings.
As a regular-use volume control, the feel is not great.
