Record Research Labs cleaning fluids - They don't require rinse cycles, and thus don't leave behind a film that requires additional work (rinsing) to remove. It also doesn't leave behind a sonic signature as most fluids do.
Record Research Labs LP#9 - Works wonderfully and is a bargain, considering I've had the same bottle for 4 years.
Record Vacuum cleaner - Beit the top of the line VPI 17.0 or the Record Doctor from Audio Advisor, record cleaning machines help you gently and effectively clean your records. I have the VPI 16.5 for the home, and the Record Doctor at the lake cabin. Both do a great job.
And of course all the other goodies mentioned above. I picked up 7 very nice microscopes at a local college auction sale on a pallet for $40, which is less than you'd pay for one good unit. The other 6 microscopes were given to other audio friends as gifts.
Regarding the torpedo level, it seems that I'd bought one from McMaster-Carr for less than $20 about 5 years ago. They may be a great place to find a quality level at a reasonable price?
