Answering my own question here...I saw a B&M 250 on e-bay. The rotors are straight, as I thought. And it has teflon strips.
Now the trick is to find a good used one (not one of those stories "a bolt went through the blower, just a new teflon strip and it would be fine" - yeah, right).
Also, I still don't know what's the opinions about them regarding build quality. I heard that the tiny B&M blowers used mild steel rotor shafts, and once worn out, no one would rebuild them. I suspect the 250 is a different animal, but that remains to be seen. Problem is, I'm sure calling Holley/Weiand would not bring straight answers (becasue they bought B&M's supercharger line, but still make Weiand blowers). Calling someone like BDS would probably result in "they're crap, you need to buy our 6-71".
