>I'm just about to order an extractor
If you have money you just want to spend on your hobby, go ahead. If you feel you need one, think it over.

Yes.

Cloth will lose small fibers and those will cause rapid crystallization. If you want crystallized honey this works fine. If not, I would not do it.

Altimately, I want very clear honey ... I've seen too much that is cloudy and would not feel comfortable selling it looking like that.
I don't feel comfortable buying honey that isn't cloudy. Clear honey usually means it's been overheated and overfiltered. I think it's a matter of educating your customers. A free taste of raw unfiltered honey will usually win them over.
