The sumiko blue point special evoIII is available as a low output and is in production. Limiting myself to $500 for a cartridge, I would look at it
as well as the audio technica at33ev and at33ptg and denon dl304, all of which can be bought for under $500 on ebay. I have used the seller 2juki
on ebay. The denon dl103r is widely praised but I have one, and it has woolly bass, colored midrange, and mistracks on loud passages.
As far as ortofons go, I have had two mc30 super cartridges, (no longer in production), but they can still be bought on ebay from william thakker
for $890, and if I had that laying around I'd buy one. Neutral, dimensional, tracks superbly.
