I bought a 30/2, S/N 0244, from Audiogon in 2020 and it was not locked down for transit correctly, and the oil in the towers was everywhere on receipt. Good news was there was no real damage, just a mess.
Brian Laker at SME was very helpful, he sent me Service Sheet 54 and I got the original seller to cough up for 4 vials of the tower fluid. I stripped the deck down, filled up the towers as per the instructions, doing every thing very slowly and taking umpteen photos, just in case. I still have them if you need any help.
Once all back together and cleaned up, the deck was superb. its the yellow platter and knob-style supply, I too was interested in the newer push-button style but I think its pricey (4000USD?).
I have a V and Dynavector 20X2L, sounds great to me, am listening to Gary Numan as I type. Best record spinner I have owned by far (LP12, rega P9, SME 20/2, 20/3).
You asked about pricing. I paid 12500 for the 30/2 with V. I had been looking online for years, and that was the best/lowest price I ever saw. There’s two on Agon now, one at 16, one at 22 (a lot newer it has to be said).
If you are anywhere near Seattle, let me know.
