My Rega RP6, Exact combo may be going back due to hum.

Interesting solution, Les. I have a P3-24 with an Exact 2. I think if I were to experiment with non Rega cartridges, I would buy the shims that can be found online. I hope to buy a RP-8 sometime down the road.

Considering the number of turntables serviced by me, I'd say that Rega is indeed budget line and it's not even close to to quality of Pioneer PL560, Yamaha YP9 and certainly my HK Rabco linear deck. 
I'm fan of linear decks and even simple Pioneer PL-L800 (can get it $200 in mint shape) can humiliate Rega on bass, detail and noise floor.
Well, too many to mention that will best in price, performance and built quality. 

Some good comments here regarding Rega TT. I have had my Planar 3/RB300 since 1984 when it was partnered with original Rega MM cart, A&R A60 Amp and lovely Heybrook HB1 speakers. Great system for the price point. I still have the A&R but the Heybrooks disintegrated.
Now a couple of years ago the Rega 240v suspended motor capacitor packed up so I replace the motor and board with expensive High Performance Motor Upgrade Kit's 24v DC motor & 'tuned' board. This is stuck on to the thin Rega plinth veneer of this model with thin adhesive foam pad so is now directly coupled to the plinth. 
After a recent oil/bearing change - which really tamed the bearing noise - I noticed a hum from the motor, most noticeable when the lid is closed. Detaching the platter/sub-platter & belt and disconnecting the amp/tonearm cables showed the motor noise was still there. A stethoscope from my partner means I can clearly hear the low frequency tone through the plinth veneer.
This sound does drop off quickly the further from the motor you listen but I without a microphone I can't say if it reached the tonearm/cartridge.

Dear @czarivey : Normally an audio item manufacturer buil its items to a price point and Rega is no exception to that marketing fact.

I don't think is overvalued. Whom started to overvalued?, certainly you did not and maybe no one started because the true is that it's not overvalued and yes we can consider it as a budget line.

At the end are the customers whom has the last word, not you or me.
