Although I haven't actually seen Alyssa Divine, I think I know where you're coming from (no pun). I also share a liking for pornstars, but I've always been unsure of her because of her high(ish) price, no OWO, and huge cost for filming (another biggie for me). So, having said all that, it's probably cos of the filming cost that's put me off.
If she's as good as Rebecca More (can anyone else be that good?!?), or Chantelle Fox, and Suzie Best (also both excellent), then she may be worth a go - TOFTT I suggest.
I saw Hannah Shaw (with Chantelle Fox) and she doesn't do OWO, and that was a great punt - I seem to be disagreeing with my own argument, so give it a go.
My own experience has been that pornstars are all pretty good punts - with only a couple of exceptions (and they were only minor gripes)
Go for it - TOFTT
