$160 looks like enormous price for such a thing. Helios 44-[any number or letter here] looks rather stylish as it is (sharp center, twirls on the corners). But it's always very cheap, not to mention ones with the aperture stuck. Replacing aperture with cardboard doesn't seem to be a complex task. You'd better find somebody willing to buy it nearby

As for the effect… I don't think it looks like "high quality thing". Bokeh shows horizontal lines – reflection of the ellipses on the cardboard aperture. Why do we need them? I'd prefer black velvet. If you try a cardboard aperture in front of another lens – doesn't it look better? Or just the same?
I say it as usual cinema watcher. I've never used anamorphic lenses myself. But I know standard Helios 44-2 enough.
