If you want a highly cost effective "upgrade," I suggest the Disc Doctor (DD) cleaning system of which you seem to be already aware. The DD approach to record cleaning is simply outstanding. The method invented by DD allows maximum cleaning, minimal expense, and efficient use of time. I have recently cleaned LPs on my VPI HW-17 Vacuum Cleaner using Record Research Lab cleaner. Then I have cleaned using DD cleaner and scrub brush. Foreign matter had caused the LP to skip in places AFTER being cleaned on the VPI, but the skips disappeared after cleaning with DD. The DD felt scrub pads seem to get into the grooves to thoroughly clean. Also, the sound of the LP has a richness not present before using DD.
The VPI HW-17 system is convenient, but not nearly as effective IMHO. Since I have been using DD for only a few days, I am now in the process of rewashing my previously cleaned LPs. My TT, a VPI HW-19 (MkII) with JMW tonearm and Shelter 501 cartridge, has never sounded better. The results of sound quality improvement are most gratifying.
