Reply to Good Dj headphones under $100?

I've seen the product review articles and stuff. But I'm wondering what the best set of cans for under $100. I remembered Ean recommending some of the Sony Studio monitor headphones but I can't find where it was or which model?

Was believeing the Sony MDR -500 or 700's?

I know it makes more sense to spend the jack and just get some top quality, but I don't have the jack, I have Jenna, she's 4 months old and has a lot of my loot tied up in her well-being a long with her mom.
