The X400 is good quality. I checked one out at Cabelas. SHEELS has the older version Refuge right now for $249. I believe Amazon has the X400 right now for $290 & free shipping with Prime. Can’t go wrong with free shipping.

Friend of mine has had a Clam Refuge for several years and he likes it. I recently purchased a Eskimo Outbreak 450i. I haven’t used it on the ice yet but I did set it up. Seems like good quality and the full door is a great option. Only thing about his Clam I didn’t like was the windows are not removable. He hasn’t had any problems with windows cracking but the visibility to see through them is becoming an issue.
