Advantages of upgrade from VPI 16.5 RCM

I wonder if any fellow A'goners have upgraded their RCMs from a VPI 16.5 to the higher end VPI models ie VPI 17 or the Typhoon 27 or any other brand eg Clearaudio, Hannl or Acoustictech and the perceived advantages, if any, of such upgrade in terms of superior cleaning etc etc. The mega bucks that some audiophiles lavish on their vinyl front end would presumably demand the best cleaning device available.Have been using a VPI 16.5 for over a year while I am satisfied that the RCM cleaning regimen(with AVIS one step and distilled water) coupled with steam cleaning does give decent results there are several lps, some fairly new , in which the pop and crackle is a constant feature,(despite anti static gun etc etc). A recent review of the VPI 27 in Soundstage, in which MM while preferring the VPI 27 over the VPI 17, did not find any distinct advantage on account of the superior cleaning power/ more powerful vaccuum motor of the VPI 27, set me thinking.
Would appreciate the advice/comments of A'goners who have done an upgrade or contemplated one.
Many thanks in anticipation.
