ScottB,
I was going to reply yesterday morning, but a family emergency
pulled me away. Pretty much what everyone has said so far
is what I would say.
Here are some other points to ponder:
ERA has paid attention to detail. The body is very high
quality, inner and outer panels are epoxy bonded together,
not glassed together like most replicas (I have not heard
whether or not RF/Tornado/MDA/CAV/GT40NZ/GT40Aus glass or bond).
Also, the ventilation system is well done. The exit vent
on the roof by the bulkhead window is pure genius.
Although the kit is less complete than others, it comes
in a further state of completion than others.
The downers - it is designed only to use a ZF. Although
the ZF is a great box, that means more $$. Also, it is a
semi-monocoque. Again, there are pros and cons to mono and
semi-mono, but one that sticks out is if you ever suffer
frame damage, spaceframes are easier to fix. And of course,
cost and wait time.
Bottom line IMHO, if you can afford the cost and wait, you
will not be disappointed. Actually, any of the mentioned
40s will not disappoint.
