Are these services worthwhile?  Do the ladies listed there accept guys who have been screened by these services?  I would appreciate any feedback.  I've discovered that you can't see anyone unless you have already seen someone here.

This is a very valid service sort of in the same vein as Room Service 2K. Both are good services, neither seem to be very popular on the west coast, but if you're a member and you travel to say, Chicago or New York or Washington, DC it would behoove you to become a member of one or both, RS2K or Date-Check.

PS I have no idea what preferred 411 is, unless you mean Phoenix411.net in which case that is an advertising site for legitimate independent and agency providers as well as the masseuse.

What you can't do is have no references and also withhold personal information about yourself and your business.  The ladies need to know you're safe.  A paid service is not necessary if you can disclose enough info about yourself.
