Elektron Musical Instruments

Hello all!
I just got into the Elektron products recently and I'm totally in love
with them.  Both of them are incredible.  But as seems to be the trend
in here, I'm having problems with them as well.  The MD is fine (knock
on wood) as far as I know, but my Sid is having major problems.

I purchased the Sid used and the day that I received it I wiggled the
PSU jack a bit and it cut power completely, deleting all patches in
the process.  It still does this from time to time and will even
delete patches between a power off and a power on (with no movement to
the unit or the PSU jack).  The PSU jack is the Elektron-supplied one
and the unit itself is about five months old, by the way.  Elektron is
being pretty cool about the situation.  I've spoke with them several
times (after the typical one week waiting period between emails) and
they have even sent me a new PSU in hopes that this would solve the
problem (it didn't). They're offering to repair it under warranty *IF*
they deem that I didn't cause the problem myself ($50 and hour repair
charge otherwise).

So I guess I need to send it back.  But here's my concerns:
1) import fees - I don't have the original paperwork;  Elektron says
it should be no problem getting it into Sweden, but they can't
guarantee that I won't by charged any fees when it comes back to the
US (where I am, by the way).  How much should I be expecting to pay here?

2) delay time - if it takes them a week on average to respond to my
emails, how long will it take them to repair the Sid and get it back
to me?

3) posts in here - a couple of people have experienced similar
problems to mine (in here) and one person even wrote that they
repaired it themselves by re-soldering the PSU plug inside the Sid.
Perhaps I should just do that instead of paying shipping/import fees
(and possibly a $50 an hour repair fee) and waiting?

So, what are your thoughts?

Joe.
