One problem is that older GPS receiver spec sheets give numbers with SA on, even though SA has been off for quite some time, so their numbers will be inherently higher.
Probably the most accurate GPS receiver today would be the Motorola M12M Timing. I would go into more detail but I'm about to head out the door. I'm sure others will chime in on this soon. There were some posts a few days ago about some new papers that were published, there is some good info on the various recent versions of the Motorola receivers... Might want to check that out.
