I was responding to the guy who said he couldn't afford an Aster. I didn't deal with the differences between RTR and kit. I just indicated that he could get an Aster for only about $500 more than the Accucraft. But, yes he'd have to build it.
The list on the FEF black kit is $7,600 and the grey kit is $7,800. You suggested that the RTR was $600 more. Hans is guessing it will be $2,000 more. Will you build the kits for $600? If so I have 3 or 4 that you could do.
