Admittedly that doesn't cover 6M&  requires 5-10w input for full output but a lot less money. Even taking into account the cost of Pennywhistle to raise the 0.5 w to the required input level it's still expensive and the shipping at $115 is ridiculous. Not for me - I'm retired and saving my pennies for Alex.

A bit of apples and oranges. Besides working with less power input, the 
German kit includes all the low pass filtering for multiple bands, T/R 
switching, and automatic band switching that is controllable by SDR 
software. The Communications Concepts amplifier does not include any of 
those things.

I'm not sure where you got the $115 shipping number from; the eBay 
listing shows free shipping to the US. I believe that number actually 
reflects VAT, not shipping costs; the listing says that the shipping to 
Europe price includes VAT. $115 would be about 20.5% tax based on the 
US$561.94 price that eBay shows me.

This is not an inexpensive kit, but the design certainly looks clean, 
the components look adequate for the intended power level, and it should 
integrate well with the HPSDR design to make a capable 100W transceiver. 
I don't think it's unreasonably priced for what you get, but individuals 
will have to make their own judgments of value.
