Upgrade from VPI HW-19 Mark IV turntable

I have a really good sounding VPI HW-19 Mark 4 table with the SAMA motor, wood body Benz H2 cartridge and a Premier MMT arm (running into an EAR 834P phono stage). Obviously the arm is probably the weak link on this setup. I have had the urge to move on and get a new turntable in the $2,000-$2,500 range (with cartridge). Would a new 'table in this price range be a big step up in sound quality, very little or none at all? I am considering VPI Scout, Music Hall 9.1, Rega's or any other suggestions. Would upgrading the arm be the best bang for the buck? Thanks in advance for your comments.
