Linear Tracker ...I was wondering

Thank you for sharing your perspective  @mijostyn. 
It had crossed my mind too. 

@jagjag, don't take everything you read as Gospel. Different linear trackers have differing amounts of horizontal effective mass. Do look into the current Trans-Fi Terrminator.

So true.
Mijo forgot to add "IMHO" ..... Again......

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

Strange choice for this Sl1200 mk5 turntable
Remember Technics SL-M3 with Linear Tracking ? There are some nice images of that old beast. Looks better than MK5 for sure ... 

You can buy a whole SL-M3 turntable with Linear Tracking for something like $1200 (i just checked on ebay).

That's quite a beast!

Just for a taste of linear tracking on a beer budget there is the much simpler SL-10.
An example of which I own.
Pretty affordable, very well built and managed to hold its own pretty well in the sonics department.
Sure it's not upper echelon but for under $400 not a bad way to dip ones toes into the water.
