Having owned a Rega RB-250 arm and now owning a SL-1200MKII with Cardas rewire done by KAB I will say I find little to no quality difference in overall performance between an SL-12xxMKII arm and the RB-250 in fact with the Cardas rewire I suggest my SL-120MKII arm performs better. Both the Rega and SL-12xxMKII arms are about the same mass, both have very close tolerance bearings and both do a superb job at tracking a record groove.
I would not bother swapping an SL-12xxMKII arm out for a Rega. The money in upgrades should more likely be as in order.
1: Cardas arm rewire, or you can but an SL-1200M5G which has improved wiring from Technics.
2: KAB fluid damper.
3: Outboard power supply.
Note you do not need any of these to have a Technics turntable that operates very well for its price (in fact it punches above its weight), a dead stock SL-12xx is a good performer but if one is looking at tweaks or upgrades I suggest as I did above.
I will be adding a fluid damper later on for my setup but as is with the Cardas rewire my SL-1200MKII with Denon DL-110 cartridge sounds KICK BUT!!!
