If you ripped a small amount of edge (less than 6 inches) you can get it repaired.  Basically they will cut a piece of replacement edge, screw it in and base weld the ski.  This will probably take a shop guy like 45 minutes or more and the shop is going to charge you about 60-80 bucks.
Or, what I would suggest.  Cut your base out, hammer your edge till it's straightish, screw it back in, get some 24 hour 5000 pound epoxy and clamp it.  Then just sand it down.  Or just cut the edge/base and fill with epoxy (this will fall out relatively quickly though).
Dynastar won't do shit for warrantywise.  Their skis are fun, but their durability is absolute garbage.  If you ride moderately hard you are going to blow an edge/sidewall in less than 5 days.
