Consumer Reports just published their list in November's issue. They tested 25 and recommend 9:
Bayer Contour Next
Bayer Breeze 2
Up & Up (Target brand)
ReliOn (Walmart brand)
Accu-Chek Compact Plus
TRUEresult Blood Glucose Monitoring System (also available under pharmacy brand names)
FreeStyle Freedom Lite
All have an excellent overall score and accuracy. Up & Up and ReliOn are the cheapest and have the cheapest test strips. This is something to consider if you don't have insurance or if your doctor has not prescribed a meter and you just want to test on your own and insurance won't cover it.
Even though these have an excellent rating, don't forget that some individual meters may still be 'off' and not as accurate as a lab.
Also, don't be surprised if you test yourself twice within a minute or two and you get different readings. Meters are only held to an accuracy rate of plus or minus 10% for any given test.
For your further information, here is the list from November 2012 with their scores:
1. Accu-Chek Aviva (89)
2. FreeStyle Freedom Lite (89)
3. Accu-Chek Compact Plus (89)
4. FreeStyle Lite (88)
5. Bayer Breeze 2 (85)
6. Up & Up (Target brand) (82)
7. ReliOn Micro (Walmart) (82)
8. One Touch UltraSmart (82)
