Why so many linn lp12s for sale

There were quite a few on Canuck Audio Mart as well. A couple of really cheap ones too in really decent shape.

I think suspended tables generally are not as popular as they were back in the day. Today so many of us use record weights and periphery rings and those are not ideal for that type of table. Avid makes a modern suspended table but even those are not hugely popular.

As DaveyF and others have said, a basic used LP12 Valhalla from back in the day is a long way off from a top flight one. In Canada the latter costs like a Honda Civic. Lots of other choices and flavours in that snack bracket from Brinkmann, Clearadio and others that were not around during the mighty Linn's heyday.

Because they are old and abundant.

There are so many for sale because they have to go somewhere.

take a chance buy one, keep till there will be none or very little for sale and make some money.
i'm selling pioneer pl560 now at $400...600 depending on condition and functionality that i was able to get for $25...30.

I sold my LP12 30 years ago complete with toilet seat stoppers for legs and compressed springs that wobble. Sota sorted that out 30 years ago by hanging the springs. My old Sota still sounds great 30 years later.
