Cheap, easy to handle fuels/oxidizers

John Cramer's latest breakthru is adding an alcohol to 50% peroxide to make a
cheap, easy to handle, easy to buy mono-propellant for his rockets.

Does anyone know more about this combination or other cheap fuel
combinations? Notice I don't consider LOX to be cheap. In large bulk quanties
it may be, but for small amounts the handling equipment costs alot. (Frozen
valves anybody?)

I remember there was an oxidizer made by dissolving a solid oxidizer in
water, what happened to that?

Also there was a hybrid rocket that had a catalyst (in? part of? was the?)
fuel so all you did was open/close the valve for peroxide and it
auto-started. You got the simple design of a mono-propellant engine but the
performance of a hybrid, not to mention a very high DensityISP. Has there
been any more developent on that?
