Since all my references are now gone, thinking of joining one of these.  Witch is better / more recommended.

Personally a member of both, seems to have different menu on each.  Happy hunting!

Date-check has a one time life-time fee.  P411 is annual.  You'll see much of the same on both sites, though, there are variations every now and then.  You can still see info in P411 if not a member so it didn't make sense to keep both going.

I used to travel to Dallas and Houston fairly regularly for business, and in both places, P411 was absolutely golden.  However, there are other cities where it is more useful to belong to another service, if you can only afford one.

I still have my P411 membership, and have often appreciated having it.  However, there are ladies out there who just use DC, or some other service.  Still, after a trial membership on DC, I decided that my situation was such that P411 made more sense for me.  I didn't have any negative experiences with DC, and this was also a few years back (they might have more ladies signed up around here), but I've never felt the need to go sign up with them again.
