CE Credits

Looking to brush up some nursing knowledge and also get approved CE Credits. Has anyone used Nurse.Com for this purpose? I contacted them and told that both the nursing boards i will be reporting to (Delware & Kentucky) will accept there credits. Just curious what others experience has been.
I never buy the 'unlimited CEU' package from any site, just pick and choose what I want from wherever I want. Have used Nurse.com, RN.com, and Western Schools. WS I think had better ones than some other sites, but people look for different things from online courses, so YMMV.

Does a site need to be listed on a BONs site as an approved provider for their CE credits to count?
