I have a custom built 04 Jamis Dakota. I got the frame NOS for about $200.
It is an all aluminum frame (some now have CF stays which do not interest me). Overall I am happy with it. I'm not sure about the new ones, but mine has v-brake and disc brake mounts which was important to me.
I have only put 500 miles on it so far this year and have no complaints. Nicely built and cleanly put together.
