I had Elan park skis back in 2005 and they were the best park skis I ever owned.  Very well built, durable, seriously underrated.
That said, I'm totally unconvinced about Triple Base tech on a park ski (or any rocker for that matter), so check if it's those or the old ones you're getting a deal on.  Bataleon use TBT on all of their boards and I hate how they ride on firm snow.  Once Elan puts TBT on some pow skis they will rule.
