I'm confused by this.  Firstly because it seems to imply that there is 
no finanicial difference between producing the A4 and A5 and secondly, 
because it seems to be implying that the GTA04A5 isn't required for case 
kits.  Could you possibly clarify these points?

You said there are about €3000 of one-off costs.  I presumed this meant 
one-off costs for each design; that is, the stencil and machine setup 
could be reused for different production runs of the same design.  When 
you said "one-off" is that per design, or per production run?


I was labouring under the impression that the A5 would enable case 
kits:

Is it the case that the A5 is needed for a complete case kit?  If it's 
not needed and it's possible to produce complete case kits for use with 
the GTA04A4, can I ask why kits are not for sale?


Thanks,
