For USD $3500, that seems a bit risky for me, although I would like to see 
one in person to more closely inspect component quality, machining, circuit 
layout, etc.  In that price range, there's quite a bit of competition.

Another issue pertains to FCC Certification.  CFR Sec 2.815 and 97.315 
address amplifier certification, including those that are imported.  But 
what's strikingly odd, is the wording under Sec 97.315(b)(3) since 11/2006:

97.315(b)(3) read together with Sec 2.815 seems to dismiss the certification 
requirement provided that an "external RF power amplifier manufactured or 
imported for the amateur service is...sold to an amateur radio operator or 
to a dealer, the amplifier is purchased in used condition by a dealer, or 
the amplifier is sold to an amateur radio operator for use at that 
operator's station."

That's the first time I've really examined that section of 97.315 since it 
was last revised on November, 15, 2006.  2.815 was concurrently changed 
pertaining to 10m operation, but 97.315(b)(3) is a real surprise as 
currently written.   I have to believe the wording did not end up exactly as 
planned.  Otherwise, we've got a logical contradiction in the intent of the 
rule.
