Eskasi:400+?? I think you mean the Elastiprene/Merino suits....the combination of both do make things much more expensive...mine was WAYY cheaper. I paid about $240 only. Merino Lined but sadly not super strechy Elastiprene which would have been much more fun to put on or remove.
Having said that, I have not issues donning or doffing really.
My LDS has them at MSRP - $415 for the partially lined 7mm, $435 for the fully lined 7mm. I don't remember what the Elastiprene goes for.
ScubaToys will order what I want for about $90 less for all of them. But that's still $325 or more. I'd like to support the LDS but I do like ScubaToys and have bought stuff from them in the past when I can't get it through my LDS.
