Jenny - ouch - sounds like a rock and hard place! As we know ASP/FIM don't usually go out of their way to accommodate and if they aren't keen on prototypes I guess it doesn't look good. :-(.
Any back up plans if it's a definite no?
Hope not though as I think the LC4-50 is a great idea!
Sorry I've been put of touch - poorly lately but better now so will give you and Martin a call about plans next week.
