I also agree.

While I would not mind getting a couple of units for tinkering, I 
already have the regular commercial version, with the DC/DC converter, 
the normal enclosure and the Trimble Bullet antenna, and the whole 
package cost me $200 with a guaranty.

Paying anywhere near that for the stripped down version, open frame 
case, no power supply and no antenna, in a quantity buy, without knowing 
if it even works would not make sense. Besides, since mine is running 
just fine, I don't really need another one. I would not mind paying $200 
for two units for tinkering purposes, but higher than that would not be 
reasonable. I think if we proceed with a group buy, we should demand 
that the seller checks them out. If necessary, I could provide 
instructions and the power supply needed to do that. At least we would 
have some assurance the thing is not just a bunch of bad units.

Someone is selling ACE-III GPS receivers for $10 for three pieces (I 
just got a set). Add a commercial grade OCXO and an N1JEZ control board, 
and you essentially have a Thunderbolt equivalent for less than $100.
