Magnifying Daylight Lamps

I know there are quite a few of my readers who are cross stitchers so I'm seeking your advice. I haven't done a lot of cross stitching in the past but when I have, I've struggled a bit to see what I'm doing, especially when there isn't a lot of daylight about.

I've got one of those contraptions which clips to the embroidery hoop, there's a small magnifier and light on it. It's okay for what it is, not brilliant, but it certainly helps. I've got a snap frame which I'd like to try out but the clip on the magnifier is too small for this and there's no way I can stitch without some kind of magnification.

I'm thinking about putting a magnifying daylight lamp on my Christmas wish list and wondered if any of you use one. I think one which stands on the floor rather than a table would be better for me and I'm sure it would come in useful for more things than cross stitch, especially during the winter months when there isn't much daylight about. I'm looking for any recommendations you can give. Do you have one of these magnifiers, can you recommend a particular one, do you find it useful, is it worth having?
