But now, thanks to macobserver.com, I found one I really like, the Satechi Readmate. It is a 5X magnifier with built-in LED lights.
It looks great, is very reasonably priced, it's optically better than anything else I've seen of the kind, and it's very practical to use.

(It seems not to be sold in Europe yet, I had to buy it from Amazon US. But it was swift and not too expensive, well worth it I thought.)
I'm also considering their combined desk lamp/magnifier 2X, which seems useful for small manual tasks and for reading paperbooks with fine print.
