I have been doing some shopping around for quotes and would like some advice please.
For the linear components the following is what I got back:

Chai = $738 = £510
Fred = $958 = £663
FYI - Local Supplier = >£3,000!!!
The shorter carriages were £100 less in total if I went for them.

Ideally it would be Chai with the shorter carriages but two disadvantages seem to be, hes using a different brand of rails/blocks and also, i'm not sure if the shorter carriages will be enough for possible long term aluminium work. What do you guys think please?

Also, does £140 sound like a good deal for all the aluminium and steel plates (gantry sides, full z axis, bearing supports, spacers, etc)?
