Looking for an Erg

To be more specific I'm looking for a Concept 2 Model D erg. Here's why - I've been involved with rowing for over 20+ years - shocking I know - but I have never ever raced a single. I have talked about racing a single for 10+ years, but honestly would rather race a double. So I've had a lot of time to think lately and have come to this conclusion - one of the things I least want to do but always talk about is racing a single. Which means it something I really have to do. So in that vein I am trying to get ready to race in 2008 (God help me!). So I'm looking for an erg to help train and develop my aerobic base, if anyone has a lead out there for me I'd appreciate it!
