All of our products are sold directly from TT USA, therefore prices are in USD and you need to add postage to that, about $60 for a Scarp 2.
You also need to seam seal it yourself or get TT to do it for you ($30USD)
On paper the FlyCreek 2 may appear to be bigger, it isn't .
This is why :


The given dimensions are the floor width and length at the corners .
With the Scarp pretty much all of the floor space is usable, not so with the Fly Creek because on three sides the mesh inner slopes inwards.
The peak height of the FC2 is 96cm, 114cm for the Scarp.
You may also want to consider that you set up all TT shelters fly first (fly and inner for the Scarps) so if you set up or take down in the rain you don't get the inner wet.
Also the Scarp 2 has two entry points/vestibules.

(note that the vestibules are smallish but you can store a 70L pack out of the way in there, they will be on the doorway in the FC2)
The design allows a drip free entry so you don't get rain onto the floor either, that helps with views and condensation management.
(in wind blown rain , well use the other door...)
Contrary to the BA description, the Fly Creek 2 does not work in "freestanding" mode, you need a minimum of 6 stakes to keep the shape and have the fly not touching the inner.
In the end you need to work out which design you like best.
