You can get one of the best lubes in the world cheap. I got mine at Lowe's for about 5$. It beats the tar out of every other bike lube I've tried, and that includes Prolink and several others (yeah, and triflow)
Dirt don't like it. It takes longer to gunk up than anything I've seen. I've used it all over the house, lubricating hinges, slides, you name it
It even works as a motorcycle lube.

Edit.. I just stumbled across this review...
"
Over the winter I picked up a can of "Dupont Teflon Multi Purpose" lubricant at Lowes. I always have problems with dry lubricants on my production woodworking machinery. It either wears off in no time leaving every moving part annoyingly squeaky, or it collects sawdust and jams up the works. I figured "what the heck?" and threw it in the cart.
The first major test were the tilt and elevation worm wheels on my cabinet saw. Not only did it instantly quiet the squeaks, but the handwheels turned like greased silk. Next were the elevation screws in the planer. Once again, smooth as silk! 6 months of daily use later and they still do, and the coating repels sawdust. Now just about every machine in the shop down to the depth adjustment on my $20 Skilsaw has a shot of this stuff.
Anyway, recently I read an article on high-speed chain lubrication. The main focus of the article was on roller wear and particulates. Specifically that tacky lubricants will collect crap and/or water and grind it between the sprockets and the chain rollers. Sound familiar? I know with normal chain lubes my chain turns black with crap in about 500 miles after a cleaning.
I went back out to the shop and found my can of Teflon spray. Says right on the can "perfect for chains". Well.... We'll see about that. I sprayed both the SV and the GS down and went riding. In the past few weeks I've put 1,000 miles on the SV and 2,000 miles on the GS, reapplying every 600 to 1000 miles. I'm amazed. The chains look like they just came out of the box and I don't notice any roller wear or chain stretch. Several people on the SV board have commented on the spray, stating that it significantly reduces the rolling resistance in side by side testing.
Anyway, I think this stuff is great. Anybody want 3/4's of a huuuuuge can of tacky, gunky, black, nasty Suzuki chain lube? If not, I'll give it to my neighbor to lube the link belt chains on his hay baler."
