At this very moment, for a Grille Ausf. M to my door via eBay, ~$32 US for Alan or ~$53 US for Dragon. 
A sealed Dragon Grille Ausf. H is already in my closet. Yay younger me. 
Cue chorus girls:
Why doesn’t he build what he has?
Oh no!

Oh ya!
It is awesome that almost every model is out there, somewhere, just waiting for the right person to build it. 
(More probably store if for free for someone else.)
