Tone arm for SOTA/ZYX

Looking for recommendations for a new tone arm for my SOTA Nova. Cart is a ZYX Airy 2. Rest of system is FS Presence Dlx2, ZYX pre-pre, Hagerman Trumpet, Joule VZN-80 and Merlin MMs. I presently have an OL Silver and would need a new armboard for it, at cost of about $280, drilled. I have an armboard for an SME arm. Resale value of OL Silver about $5-600? Resale value of SME armboard about $125. Don't mind spending some additional $, but not ready to go whole hog on a super arm. Should I just get a new board for the OL Silver, look at a used SME Mk IV or V at about $1400-1600, or try something else? Should be relatively easy to set up and stay set up, if you know what I mean. This is a secondary source for me due to my hectic schedule. TIA
