Well, we've wandered pretty far off topic with the discussion of what form of payment is best...but worse than that, we're talking about the wrong thing.
What form of payment is best?
ANY form of payment from an honest remitter is fine. I know a lot of DVC owners who routinely take personal checks (which would be at the bottom of the list for most posters on this thread, I suspect), and they've never had a problem.
And conversely, any imaginable method of payment is subject to counterfeiting, bouncing, fraud, etc.
The method of payment is only an important issue if you think the other party may rip you off. And if you think that...why are you renting to them in the first place???
The question of some sort of feedback mechanism is the same conversation. That's a method of firmly slamming the barn door after all the horses have been stolen. Why not just avoid that problem altogether?
I think a much more useful discussion would be ways by which both owners renting points, and those renting from them, can assure themselves that they are dealing with a reputable person.
The only real protection anyone will ever have in a rental transaction is trust -- and trust is earned, not given. There is no substitute for due diligence -- and there is also no excuse for not doing your homework.
Another critical element of a successful rental transaction, IMHO, is that both parties
clearly understand all of the implications and ramifications of the rental transaction. In fact, most of the problems we see with rental transactions are caused by
misunderstandings, not by evil fraudsters lurking behind every computer keyboard.
I really think that would be an interesting discussion, but I think it would be better on another thread.
