There are some really good used phono pres in the >$1k range and it really comes down to needed gain & personal preference.
I owned the Graham Slee Era Gold mkV ($999 new, ~$550 used) and it was excellent. It's good with carts between 2mV - 9mV output. I compared it with the another over-performer in that price range, the tubed EAR 834P, which is also excellent - especially with a few simple upgrades. It really was a toss up between the two, both were great.
You really cannot go wrong with either of those two.
