Imagine if you were new to WNW, or even to WWI modelling, and investigated buying your first one.
I reckon you would select the model you want for all the usual reasons of choice, including price. The fact that it may cost a few AUS$ or Euros more today than a few months ago, would make little difference. You can either afford to buy the kit you want, or you can't.
If you want an expensive kit, such as the Felixstowe, a few $ more won't make much difference? If you have the money to spare already, then you probably have enough cash to cope. If you (like me) need to save for the kit, then another month or so to wait in what may take a year anyway, again doesn't make much difference - if you really want that kit...
