But who is going to get it "for you"?
I contacted them and they refused to even send information as to quote 
them" our amps are not FCC approved" so we can't sell in the US. So I 
would assume they are not generally available in the US.
My preference for manual tuned amps (so far) is the Emtron DX-2sp, which 
is rugged, capable of the legal limit 24 X 7 any mode. I have no 
complaints with the operation of the amp after about 9 months of use.  
The only thing I would change would be separate toroids on 160, 75, and 40.

For solid state I'd go with the Tokyo Hy-Power legal limit amp, 160-10. 
I had the smaller 1.5-Kfx for a while and it was a great amp with a fit 
and finish second to none. Worked well too<:-)). It was a bit of a 
headache to hook up to the little Yaesu FT897D, but easy to hook to the 
full size Yaesus (came with cables for that) and the Icom 756Pro or 
7000.  It was completely plug and play with the exception of the 897D, 
but all you had to do was make a cable.
OTOH it was very fussy about SWR. Past 1.1:1 you would see the power 
drop off, so a tuner was a necessity.  OTOH add the auto tuner and you 
are in business for instant band hopping. The only fault I had was 1KW 
on 160-10 and 800 W on six, but it did give 800 W more than most on six.
