Spread and Size on a 100 up Market

[EuSouBitcoin]

For a 100-up market I show
BitFloor 22.49 to 22.50  188x184
Mt Gox 22.56 to 22.67  170x391

What do the other exchanges look like for a 100-up market size?

BitFloor with a 1 cent spread VS an 11 cent spread on Mt Gox, what's up with that? I know if you are looking for a 1,000-up market that Mt Gox is the best, but for trades of a 100 BTC there may be some good alternatives.
