A Shelter 501 would do just fine for $800, and sound great. Very musical cartridge, with quite a bit of "Koetsu-like magic" and excellent at detail retrieval, without sounding analytical.
The Shelter 901 is better at detail retrieval, but loses some of the "Koetsu-like magic", and is more analytical. Still one of the best cartridges made, though. $1500.
ZYX R-100 FUJI is an excellent alternative to the Shelter cartridges, at a slightly higher compliance and more money. Also a very killer cartridge, and you may like the higher compliance sound and tracking ability of those types of cartridges. Compliance is similar to Benz, but the ZYX have the very musical "Japanese" MC sound, which I personally prefer over the Euro cartridges.
