GREAT deal! Good job on that bargain shopping! Let's go to the mall!
Oh... wait... sorry... you probably don't do the mall...
I have a 23c2 and I love it. I've only used a dichro head a couple times, and I have to say that even though changing out the filters on the condenser gets to be a PITA, I still love the sharpness of it.
But congrats on your deal! I hope it all works out for both of you (you & son...bighead jr????)
