Under $2K new with that combination of features, you'll probably be limited to Turkish guns (Huglu, DeHaan, CZ, Armsco, etc.)
Used, still tough to find POW/Round Knob with Schnable and 30" barrels at that price. Browning Feather or Feather XS has 30" w/ Schnable, but full PG, around $1500. Sig SA5 has round knob w/ Schnable, but 28" barrels, also around $1500. There may still be some FAIR Rizzinis around with the specs you want. Best bet may be a Citori that needs to have the wood refinished, and reshape the grip as part of that refinish. Should come in well under $2K.
