There are many linear tracking arms, here are the ones I know of that are currently being produced:
Rockport. (USA)
Walker (USA)
Eminent Technology (USA)
Clear Audio (Germany)
Air Tangent ( Sweden)
I am not certain if all of these may be purchased separately, or even if you would be willing to pay the price (some of these are VERY expensive).
The second part of your question is YES, linear tracking provides better performance than pivotal arms.
The best pivotal arms such as Graham, SME, VPI and others track the LP inaccurately for most of the side. A properly set up linear arm is correct for most of the LP.
I have owned many turntables, and on these at least six linear tracking and more than 15 pivotal arms. The best turntables I owned, were the VPI with Eminent Technology (with upgrade pump), Versa Dynamics (linear tracking) Basis Mk 5, with Airtangent Arm (linear tracking), Walker with Walker arm (linear tracking).
These setups cover a period of more than fifteen years, so consider the era when comparing these setups.
