Linn LP12 turntable


I was in my favorite audio store yesterday talking turntables… Rega P10, MoFi MasterDeck etc, when he stated he had a Linn LP12 he was selling for a customer at $2,400 & the customer had $14K (with upgrades) into it. Intriguing, but knew nothing about Linn. After my research, people seem to love it or hate it. But it is installed in many fine audiogon systems. 
I would like your thoughts and recommendations. 
I have asked the following questions of the dealer: 

1. Date of production 

2. Upgrades that have been added 

3. Power supply / tone arm

4. Condition 

5. Recently serviced

I have not yet seen it, but it is there now. What other questions should I ask?

My current analog system: 

Pro-ject 1xpression carbon classic with Hana ML

Rega Aria

PS Audio BHK pre

Simaudio Moon 330A amp

KEF R11’s

Advise would be greatly appreciated.

New ones probably sold out at that bargain price, especially since I think they’re limited production (maybe 50 units?).

According to the guy selling it, they made 250 and of course "They're reported to be almost sold out." 🙄😆

There is an engraved with Ivor Tiefenbrun signature 25 year anniversary edition SME tonearm, Majik power supply on eBay for just over $4k. I can only imagine the long term depreciation of this 50 year anniversary model. 
I am not sure why, but the internal phono stage for both the 50th anniversary & Klimax does Analog to digital conversions. I am sure they have their reasons, but not something I would ever want… regardless of how well done, turntables & phono stages should be pure analog IMHO.
