Adam...the thing is that by industry standards a meeter can be off by as much as 20% and still be acceptable! Manufacturers can claim all the accuracy they like, but usually the "testing" that showed that is funded by the manufacturer themselves.
If you find one that exactly matches the lab results, let me know because I'll probably be out looking for it soon after!
I currently use an AccuCheck Advantage and it seems to give me readings that are fairly close to what the lab results show, if not a bit on the high side. If I had to choose, I'd rather that my meeter register high than low since hypos are only very rarely a problem for me.
