<font color='#000080'>Fi,
I have had a ND Vortex for 4 years and am very happy with it. Mine was off the peg but fits very well and quite tailored with the elasticated waist. Plenty of room for movement. I couldn't comment on the fit for ladies, but if I remember right it wasn't a lot more to get one made to measure anyway.
The internal braces are useful and the neoprene ankles on the boots are quite snug and so prevent too much air getting into the boots and giving you floaty feet.
I've had no problems with it at all, except for a puncture hole which could of course happen to any suit. ND repaired it quickly and cheaply.
It's great value as, for around the price you're talking about, I got a good undersuit thrown in aswell.
When I was last there (getting the puncture repaired) I looked at their new Cortex membrane suit. Nice. It looked absolutely bomb proof; made from Cordura. I don't know how much it is but if it's not too much more it should be worth considering.
I havn't tried the others on your list so can't give a comparison, but I hope this helps.
Mark.
