None are really very good. The HMC40 is OK. You really have only two choices:
Go with a large sensor video camera the EX1/3 and HPX500 being about the cheapest. OR go with a HDSLR like the 7D
(fully pimped out one); yes that's Robert Rodriguez behind the franken cam. Expect to spend big bucks to get a functional video camera though and consider a vest type camera stabilizer unless you are going for the
Blair Witch shaky cam look.
