Buggsy,
As with all things, YMMV as far as whether the woman in the pic on a CL post is really the one you'll get. Most (but not all) of the asian ads, though, seem to have semi-representative pics, and the price (usually $. 6/hr) is pretty standard. The catch is that some of the places give you a full hour, while at others you might end up only getting 45 minutes. Best approach: see if they number matches up to a report on one of the review lists and see what (if anything) the reviews say. Most of the "established" asian establishments have been around long enough to collect a few reviews, and even if you don't find anything, it doesn't cost you anything but the time.
Hope some of that helps.
