Mountain Biking - Knobby 26x1.5" Tires - Where can I find some??

Where the hell can I find 26x.1.5" knobby tires? I'd like some for cyclocross/snow, but everywhere I look seems to be sold out/discontinued.

QBP - Discontinued and/or sold out of Michelin/Continental
J&B Importers - Only carries slicks, not knobby.
Bike tires direct - Carries only 2.0" or above.

This thread could belong in cyclocross, but since cyclocross is technically 700c, I thought this belonged better in MTB.

not the most aggressive, but look alright

schwalbe makes a few. check out their site cx pro hs 269(1.35) (http://www.schwalbetires.com/node/1396), the black shark mud(1.5) (http://www.schwalbetires.com/node/1359)

I use these

I was somewhat the opposite...trying to turn my old Giant Rincon hardtail into a "semi-road bike" for winter use with a not slick, not knobby tire. I found these which seemed to fit the bill:

According to Schwalbe's ratings it seemed to be a fast, grippy tire, exactly what i was looking for. User reviews seemed very positive too.

Is it my imagination that it seems that companies aren't making as many thinner 26" tires since CX really got going?

@khatfull: I think you're right. It seems both continental & michelin have stopped producing/supplying their 1.5 26" tires since cx has become more popular. Perhaps most CXers are using 700c? I dunno...
