ASV for PCI compliance

A bit behind on this, but trying to find an Approved Scanning Vendor to get PCI compliant. I use either an Omni Verifone 3750 or Firstdata FD100 terminal connected via IP for all of my credit card processing at our various locations. Firstdata recommends securitymetrics.com, however, they charge $699 per year for quarterly network scans. Trying to find someone with a reasonable price among the 154 approved scanning vendors listed on the PCI council website has proven to be very time consuming. Anyone using an ASV with reasonable prices? Thanks,

Jonathan
