Sadly, there's about 3 of these somewhere in this forum....problem is the die...and people just generally don't care and just make their own thread anyways.
iSteeze - Any price point ski (usually between $150-$300 for current seasons) would make a good beginner park ski. Most skis will last the first season or two of park. Here's some decent price point skis out there:
Armada El Rey - Stiffer, No Rocker, lightweight good cruiser and park ski (been called the best price point ski on the market)
K2 Press - Soft, Rockered, decent beginner ski, a bit heavy though
Line Mastermind - Soft, No rocker, lightweight, decent beginner park ski
Surface No Time - Mid-soft, Rocker, lightweight, good all-level park ski, previous versions have had some durability issues though
Rossignol Sprayer (also previously called the S1) - stiff, lightweight, good beginner/intermediate park ski, awesome carver too.
I'd personally go for the Armada or the Rossi price point skis if you can afford them, they're really fun and will be able to shred the park and the groomers both really well.
Don't be afraid of previous years gear too, you can save a few bucks and they're pretty much the same thing usually just different graphics.
