Middleman Comic - Free!:
Viper Comics has posted a free PDF of Middleman Issue One. I enjoy this book quite a bit, it's written by Javier Grillo-Marxuach (of Lost) and has nice black and white artwork from Les McClaine. If you like it, the first trade is only $10 and the new series has a 99 cent first issue, so it's cheap to get into.
Definitely worth a look.
