dunno if i know about 'em better than most, but i *do* know that i got a good deal on an origin-live modded rb250 from stoneaudio uk. i tink ewe can also buy 'em direct from origin-live. in the usa, i believe galen carol audio sells 'em. killer arm, really nice on my oracle 'table. origin-live sez it's their best arm - even better than their modified rb900. the 900 has better-quality bearings, but the more rigid bearing mounting of the 250 works better after the mods are done (according to o-l).
