Is there an easy way to view how many bitcoins are willing to be bought at the highest bid price and how many bitcoins are willing to be sold at the lowest ask price? I know certain sites may show these values, like localbitcoins.com - but I'm looking for something exchange based. I haven't seen a way to really see the big/ask size on Mt. Gox
MtGoxLive will show a popup with that number if you hover over the depth line (either for bids or the asks):
