+1. Using these MFT-style work surfaces with a TS55 has transformed the way I'm able to work. I'm limited for space in my workshop, and these have made all the difference.
I have all the usual TS 55 accessories, and can also vouch for Peter Parfitt's Parf Dogs, which are an excellent value accessory for these tables. One thing to note though is that if you have the current Bosch plunge saw, you will need to have a thin piece of material to lay between your track and the Parf dogs, as the sole plate will not clear them without a spacer strip.
I produce my own 'MFT-style' work surface, and have just started to produce them for others, too. They are 1220 x 600 x 18 Norbord Pro MDF. Holes are 20mm diameter at 100mm centres, which gives a healthy 66 holes per work surface. I use CNC machined templates, which allows me to produce perfectly aligned holes. They're are various options depending on what they're mounted to, but a standard top as described would be £35. I personally use a 1220 x 600 folding table by 'Life-Time' (Costco). I've just made one to mount to Keter folding workbench (Screwfix), and was very impressed by it. Very versatile and sturdy bit of kit, which folds away to a fairly small size 'case' in seconds. Only concern for me would be the availability of spare clamps, as they are proprietary to that bench.
If this helps anyone, feel free to contact me.
