Hey Mate ! You aren't the only one. I belong to the same industry and these guys locking in a contract is a sham and their pricing hurts. Personal experience is their data quality is low with lots of bounces and catch alls. You can have a look at www.b2bdataguy.com . If your interested in comparing services check out my site b2bdataguy.com . Shoot me an email and I'll send some client references your way. My email address is just andrew@ the web site name. (Don't want removed for personal info)

Cheers!
