[member=72953]Josh2[/member] - your question and your comment about $ 600 needed to make successful paraqllel cuts are understandable. we, TSO have not done a good job of explaining the choices available.
In it's second year of production the TSO TPG Parallel Guide users have taught us a number of things:
Nearly all buyers of the TSO Parallel GUide already have, or will buy, at least one GRS-16 Guide Rail Square. Why? - you need to make SQUARE cuts all the time. So the GRS-16 is a foundational tool for the growing number of woodworkers using Track Saws. It is also part of a flexible SYSTEM that you can mix and match to your particular task.
If you buy no other accessory for your Festool or Makita track saw, buy a GRS-16 or the -PE version.
You can't go wrong. TSO pioneered the category. It is such a global success that FESTOOL approached us about a cooperatve arrangement. Today FESTOOL sells our patented GRS-16 PE version (made in Germany) globally outside North America while TSO supplies USA and Canada. You can't choose better than that.
Now for the Parallel Guide question:
Almost half of our customers have bought the TPG-20-30 RIGHT Hand Set to use with a GRS-16. This gives them square AND parallel cuts in one set-up for workpieces of less than full sheet length.
As Tom mentioned in his post above, his shop has proven that full length parallel cuts can be made mit just one GRS-16 and T-tracks on the RIGHT Hand side. As a practical matter you'll likely be making shorter parallel cuts most of the time.
That capability can be had for $ 149.00.

To use a pair ot T-tracks, the $ 49.95 Track ADAPTER can take the place of a second GRS-16.
