Really look at your total cost.
The current Festool Oz promo brochure offers ...
TS55R + CT26 + FS1400 Rail + Rail bag for a total cost of $1895.

This is a CT26 over a CT Midi.
Now your UK price with a Midi only is $1380 + $138 + $155 ... thats already $1673 ... for that you get a lesser package. But that's not all, now you have to get a new module for the Ct Midi power outlet, re-terminate the vac power cord and also get a new plug-it lead for the TS55R ... at least $200.
... and still no warranty!!!
Get good and friendly with a local Festool dealer and look for the best times to buy.
Don't under estimate the value of a 3 year warranty and local dealer support. Also make sure you add up the complete cost.
Oz spec machines are a shorter run at Festool Germany ... minor - but yet another price component to be aware of.
Another little thing, if you check the prices on accessories and consumables, they've dropper across the board in the last month.
