I've been using Oster Classic 76's for a few months. Kind of expensive, but they are quite nice. And you can buy various size blades to use with them.
Andis makes a #000000 (.1mm) blade that fits them (I've been using this one for about a month or so.)
They also come with a #000 (.5mm) blade that might be around the size you'd like.
If not, they also have a #0000 (.25mm) and #00000 (.2mm) that would be the middle ground between them.
There are a whole range of blades you can buy, and they seem very high quality.
