WOAH WOAH WOAH!, You lived in the holy grail of snowboarding and you moved to go snowboard somewhere else!? OH NOES!, anyways I'd checkout these sites and these brands.
For good brands I'd look at.
GNU
libtech
Omatic
Stepchild
Capita
Neversummer
K2
Forum
Rome
Bataleon
Avoid pretty much all the brands sold at those big retail stores "D&icks,sports check,sports authority,big 5 ect ect". Pretty much all the brands sold there "5150,Lamar,LTD,Sims,morrow" are low end garbage decks that any boarder planning to go a lot shouldn't bother buying, They'll only end up holding you back.
