6x9 negatives are amazing... You should definitely get the camera.
I presently have two enlargers but both are only 6x6. I just got out of the darkroom and was printing a couple of 6x9 negatives using my 6x6 carrier onto 8x10 paper, so quite a bit of a crop but I got two really good prints. I'll eventually try to get a larger enlarger.
Trying a contact print or two sounds like a good idea as well. Will have to try that one day.
