While I'm curious and live near Philly I'm also, shall we say, CHEAP. $10+s/h for 10cc is a non-starter for me, especially since I bet I can find something suitable without 3 YEARS(!?!) of research. I know a few Mech Engineers who'll educate me WHILE they laugh about my newest compulsion. I've got a red&white tube of singer lube that came with the 15-91 I bought for $9 last week. Probably a used up metal tube somewhere too.
See? Why would I forego an entire machine and cabinet in favor of a tube-a-lube?
Altho it WOULD take up less space.
