I got my lamps from IKEA several years ago on sale for $11 apiece. Ace hardware has the magnets for about $5. Also, they have them in different strengths. Instead of an 80 pound force magnet, I got 25 pound force magnets which are just the right strength for firmly holding the lamps in any position and still easy to move around. The switches on mine have worked without problems. The only problem so far was when I ran over the wire while sliding the tailstock. It doesn't take much to shear that tiny wire.
