If you take the leap to a REGA RP6 or even a RP3 with upgrades, you will find that the technics sounded THIN compared to the huge soudstage and fleshy images you will get with a REGA table and a EXACT/ Dynavector 10x5 cartridge. Any other table is moving sideways IMO.

My experience was totally contrary with Rega P3(terrible deck and great arm). I found that Rega P3 sounded FLAT and buzzzzed lots. It lasted couple of month in my system and I found that even stock SL1200 humiliates Rega P3 with greater tonal balance and clearer midrange. Bass was also tighter and substantially faster.
Invest your money into upgrading SL1200 arm, arm-board, because the quality of this deck is substantially higher of any Rega in the market.
