I second the recommendation of the J. Allaerts MC1B. However, the pricetag of $2300 is more than double your budget. I've been listening to one for the last two months. It clearly outperforms the cartridges that I've had. (Denon 103, 103D, Shelter 501,901) I'm even inclined to say that this will be my last cartridge. I'm done searching.
It's true that there is a long waiting period. The US distributor is Audioadvancements.
