I'm an original Axis owner since 1988. I love the sound of this table, so much so that I had it refurbished by a Linn service tech about 2013, 14. I would be wary of buying an old table without knowing its history. The safe bet is to keep the Project and do some upgrades.
The reason to be wary of the Axis is due to the lack of available parts for service. The motor is attached underneath and is one of the vulnerable parts. There are no more to be found. A motor would need to be harvested from another Axis. If the seller can verify that the service on this unit included more than a recap, then it may be worth purchasing.
Back when it was first introduced there was very little difference in sound when compared to the LP12. It still has the Linn family sound.
