Two Arm Turntables

Although I have nice VPI Scout now, I am thinking about upgrading to a new turntable, one with two arms. I want to be able to very conveniently (i.e. no switching wands+vta settings, etc.) switch between mono and stereo cartridges, and check out some arms other than the VPI JMW. I was thinking about $6K, ex-arms, used, preferably (much) lower (although I don't want to get upgradeitis again, a most expensive condition), as going beyond this amount seems ridiculous. Ideas so far: Garrard 301 with custom plinth, Verdier Platine, Micro Seiki 5000 (hard to find arm boards?), and TW Acustic Raven Two. Well, hard to find these used, especially from a dealer...but I'm patient. Other ideas would be much appreciated. Thanks, Mark
