If you're happy with Feet and Knots, the additional
costs of a couple of instruments, after shipping from
Europe are minor.
Why not haggle the price down a bit, and leave them
with the seller, use discount to buy new ASI and altimeter

I really wouldn't worry about the ASI. I fly my Open
Cirrus (in the UK)
on metric instruments. Its stall speed is lower than
most glass gliders
at (book figure) 63 kph. If I try to fly the approach
at 50 kph,
mistaking this for kt, I will realise my mistake in
plenty of time to
correct the stall. I must say that because the difference
is nearly 100%
between kt and kph I've never had a moment's confusion.
I can't imagine
anyone having this problem on the launch either, as
the aircraft won't
be flying at the 55 kph mark.

Agreed. I've done virtually all my gliding in the UK
using kts/ft
instruments. However, in 2003 I visited the Wasserkruppe
and flew there
with no problems. Check ride was in an ASK-21. The
ASI was the same model
with the same coloured snake but a different numeric
scale. My club has a
couple of ASK-21s which I fly fairly regularly, so
I know the sounds and
where the needle should point so I had no problems.
They then gave me a
flight in an ASK-23, which I'd not flown before, but
this time I was
briefed with the right speeds, so again no problem.

I was more bothered flying a kts/ft ASK-21 in America
than I was flying
the German metric one because for some reason known
only to history and
the FAA, American ASIs are upside down: at cruising
speed the needle is
straight down, not upright as it should be.
