I owned the Decware amps before Steve and had a pair which is a very worthwhile upgrade taking the amps up from almost two watts to almost 6 watts.
Trouble is that there are just not that may of them around. I had to import one from America the other from New Zealand. However provided your speakers are up to it 96db minimum sens they will reward you in spades....oh! you will need a high quality source too are they are very transparent and will show downstream any deficiancy upstream.
I do know where the other amp went to, and the guy is a bit of a box swopper so there is a chance the other amp may now be available as its probably 12 months since I moved them on.
It seems the second amp has already moved on and found a new home sorry. Your best bet will be to scour ebay worldwide, they come up for sale surprisingly often, and import one.
