If you are looking for killer base layer check out airblaster's ninja suit. I picked one up last year and pretty much never wanted to take it off. This year they introduced one with merino wool which is great. Highly recommend them.
As far as outerwear goes... I have Ride outerwear, 686, Bonfire and Burton. All of them are very nice, even Burton (only use their outerwear). You definitely get what you pay for and I don't buy anything unless it is at least 15k waterproof. Look for higher waterproof ratings as that is key.
My typical riding outfit for a 30 degree day is ninja suit base layer, snowboard socks, snowboard pants (I only wear shell pants and long underwear and my legs stay warm), zip-up sweatshirt, snowboard jacket (most of my jackets have minimal insulation or none at all), gloves and beanie. Sometimes when it is SUPER cold, such as 0 or below, I will wear my 686 pants that have a zip in liner and I will also toss on another long underwear shirt that I have from Cabela's.
