Multiple FS AMP visits, I wouldn't even have to think about it.
$1500 is way beyond what I could ever imagine, but I've splurged a few times (relative to my modest budget) on escorts whose rates these days would be in the $500/hr range. And they were *very* nice, gorgeous, and the sessions were excellent. But not so much better than an AMP visit that I'm willing to do without for months to save up. And it's hard to imagine that I'd get triple the experience at triple the rate.
Plus I've found as I learn how things work in FS AMPs, and as I've become a semi-regular at a couple of places, my times there have gotten much better than they were in the beginning.
