Dan, I'm curious what you hope to gain from the PGS for your small Bench Top Bench. The genius in the PGS is in its ability to allow you to lay out an array of 20mm holes in a near cnc accurate pattern, most typically for use with a track saw, but also for woodworking tasks that can take advantage of a larger array than your Bench Top Bench.
My imagination may be lacking but I can't envision a benefit from having the precise layout of holes provided by the PGS on such a small surface, let alone the complexity of setting up the Bench Top into a fixture/jig to allow the Parf Sticks to function per design. (Ideally, they can use a meter-square work surface to take advantage of their inherent designed accuracy).
Clearly, the PGS would be ideal for fabricating a new top for your 1080 or a new MFT, and several of its components might be very useful in drilling the dog holes for your Bench Top Bench.
As a matter if information, I recently received my PGS from Axminster here in Florida; the invoice cost was £99.96, $123.40US. I bought several other items, among them a couple guide rail clamps that appear to be identical to Festool items that sell for $43 a pair that Axminster gets $8/ea for. Wish I'd bought several.
The PGS came with the round shank 20mm drill bit, I bought a an extra, centrotec shanked bit and stop collar for $25.67 just because. I ordered my PGS a week or so before Peter Parfitt announced the change to the centrotec bit being included in the PGS.
Best, Gary
Edit: Oops. My bad. As noted below, My info about the 20mm drill bit included with the PGS was wrong. Apologies. Thanks, squarecut.
