Can someone recommend a good digital scale

I have this one
Jewel Watches LCD Display Precision Digital Gram Jewelry Scale 2g x .1g 6397522563 | eBay

And it works fine over 5g, I bought some certified calibration weights to verify accuracy, but it sucks under 5g.
I'm looking for one that is accurate down to at least 0.5g
There are so many choices that claim there accurate down to .1g, but has anyone bought one that they know first hand is accurate

If so please post a link I would really appreciate it
Thanks
