Is ext3 on a flash medium really a good idea? At least cheap flash
drives probably don't have smart wear levelling.

And FAT32 is better?



Let's us all start a movement, an exFat on Linux movement. exFat is a relatively new FS that is designed specifically for removable drives. It is superficially an "extended FAT", while the underlying bits are new. MS has added it to Vista with SP1, and to XP with a hotfix.

Everyone should hope someone competent takes the time to port it to Linux, with full write capability. It is exactly what OP needs.

In the meantime, for removable drives 32G and under, one should probably stick to FAT32/vfat.

I disagree. Linux already has jffs2 for embedded flash applications. http://en.wikipedia.org/wiki/JFFS2

However flash drives have their own controller:

Removable flash memory cards and USB flash drives have built-in controllers to perform wear-levelling and error correction so use of a specific flash file system does not add any benefit.
