I have a very nice magnifying lamp from Lee Valley Tools (http://www.leevalley.com
). I can't find it on their web site though so they may not sell it any more.
I'll try to look up the exact model number.
The model number is 8093. A quick google search for magnifying lamp 8093 turns up a few places including this one: http://www.gsmserver.com/shop/equipment ... p_8093.php
Like I said, I got mine at Lee Valley Tools and have been happy with it.
