I realize this approaches blasphemy, but just a quick note to say I'm 
getting a tad under 500 watts (steady whistle) out of an Icom PW-1 when 
driving it with my KX3 set for 12 watts out.  At this drive level, I didn't 
bother to connect the ALC but the amp still has it's SWR etc. safety 
features enabled.  It didn't like it when I had my 40M dipole selected and 
tried transmitting on 14 MHz.!

The PW-1's are going for around $3k and DO have a decent antenna matcher 
inside.   Admittedly, this makes for a much larger station package, but if 
you get a good deal on one, it might be an alternative.  Especially if you 
also own a K3.

That said, remember, if you're 20 over S-9 at a kilowatt, you'll still be 
S-5 at 100 milliwatts.
