The agent is more than the mod rocker? Where are you seeing these prices? You should be able to find the agent for around the same price as the mod rocker, if not a bit lower. (Althought I think I saw the 11-12 mod rocker going for what...$250, $280 nowadays?)
Maybe look into wide boards? Whats your foot size? (They make an Agent Wide I believe...could be wrong. I know for a fact they make an Agent Rocker Wide, which is also something to consider...basically the same board as the Mod Rocker).
