If I think I might want to keep it, I would buy used, mull it over and then if I didn't like I could resell later at minimal loss. There is still a hassle factor, luck, shipping costs, paypal/ebay feels, etc. It's rarely a total break even thing - especially if you don't have the luxury of spending lots of time looking for the best deal.
If I knew for a fact I was not going to keep it, $50 for a weeks' rental is probably safer and hassle free.
I'm with you, just find a good deal, buy the lens, try it out, resell it. I could only imagine what it would have cost via rental to have tried all the lenses I have. I would definitely rent a lens that I know I have no chance of buying or owning though.
