Linear Tracker ...I was wondering


Is there a not too expensive (less than $¹⁰⁰⁰) and good linear tracking tonearm that I could mount on my SL1200MK5?

Technics SL-10 is hard to find "in a good shape", over 5 years of research almost every unit i've seen for sale required service, and most functions does not work. Belt replacement requires, lubrication, cleaning etc. There are some nice units already serviced, but the price is crazy nowadays, especially if there is a Technics P205c mk4 cartridge instead of mk3 (or some cheap junk p-mount).  
I must have struck lucky then Chakster and I will count my blessings!
Picked mine up of eBay few years back, working perfectly but no cartridge.
Got three different p mounts now ( no NOT cheap junk p mount ones).
Sure it does not have quite the same SQ as my 401/505 combo but for the price it does not embarrass itself in my main system at all.

A precursor of what might come next I may add......

You can't stop the signal!
That's cool. I wish to have SL-15 in collection, i already have P205c mk4 cartridge :) 
Jag, you might wonder how a $1000 low-production tonearm could compete with a $5000 unit from a big manufacturer. The answer is, "off-the-shelf."

The Terminator uses clever engineering instead of gobs of custom machining and pretty plating. Everything is made from off-the-shelf industrial material. The most common procedures are drilling and 90 degree straight cuts - cheap.

Few curves or slots. No plating, no exotic materials, no sculpted elements. Even the air bearing is improvised from common angle stock. Just utilitarian pieces, mostly made from common aluminum shapes. Good engineering, not eye candy. Obviously, from the comments, not for everyone.

That Technics MC pmount cart would likely cost more than my SL-10 did , IF one could find one that is!
Derenville makes an 'active' linear tracker, an fyi for those posting on that topic. It is not inexpensive...
