I have fabricated a DIY RCM based on a Monks/Loricraft design which uses a Sears 2 gallon 1.5 peak HP shop vac. It sells for about $25. As with any small shop vac, the thing is ridiculously loud in use. The irony would be too bitter to incur hearing damage due to judicious record cleaning using this thing so always wear earplugs or muffs. The saving grace is that the entire contraption cost under $50.
Don't know what type of vacuum unit is in a VPI. A 16.5 is pretty loud in use also but still nowhere near as bad as a shop vac.
