Bookmarked.
I have a small active loop antenna, but I dont find it real useful for Dxing. It is however excellent at tuning out axial noise
I can solder in my sleep and that kit looks like fun
You also might like this other kit from Ramsey, the SM100 - Signal Magnet Noise Reduction Kit.
I never bought this one, but you can read the manual here.
Also, here's the manual for the AA7C.
