Whoa. I suggest forgetting the record cleaning machine and getting a steamer for the really dirty ones followed with the Disc Doctor cleaning system. (Bottles of fluid and a set of brushes).
I've got way more invested in my cartridge than you and get incredible results without a RCM. You'll get a higher return on investment by imrpoving your cartridge instead of saving for a RCM, IMHO.
BTW, a scratch significant enough to rip the styllus off a MC cartridge is going to be very obvious. If you have no horrendous looking scratches and you clean the records, you should listen with no fear for your cartridge. Scratches that cause pops within the dynamic range of the music or even slightly higher pose no risk to any cartridges.
