If you want some more core stuff like SAGA check out Lethal Descent and First Drop. You will probably have to wait until next season to get it though, and you definitely won't be unique on the hill if that matters to you. I also can't vouch for the quality/durability of these companies because I have never owned a suit from any them.
A company that I really like is RipCurl. Not too many skiers wear it and their stuff is pretty durable and the waterproofing is good. Oakley makes really cool looking suits, but in my opinion the quality is no longer there. Orage and Heli Hansen make wicked stuff but are very expensive.
