I have a Scotty Newport 2 Teryllium Longneck (face-balanced) from the 1990's. You would be hard-pressed to find one of those for less than $600. Beware...if something like that is offered for a "cheap price", something is wrong..possibly counterfeit. Good luck in your search.

I have many LN putters in my collection; few are cheap since they are not often found. However your best is to find one in rough condition and have it restored. IMHO

Good luck!

I recently purchased an old Tei3 Newport Long neck. It cost me $550 but worth every penny, I also upgraded the grip. The long neck just makes me square every time at impact. This will be my club for a very long time now. Plus it feels so soft with the insert.

A number of years ago, I found one of these at a golf club reseller. Try sites like 2ndswing.com, 3balls.com, etc. I was very happy with the price and condition of the LN Teryllium that I received, but pricing has gone up substantially since then.
