Homebrew PCBs

Hello,

I am just diving into to PCB design. What etchant do you recommend 
for starting out using toner transfer methods. I am not wanting to 
buy any hotplates or special tanks just use some old plastic 
tupperware.

Also what is the proper way of disposing any used etchant?  Are there 
places to bring used etchant, neutralizing solutions?
I live in an apartment and dont think it would be a good idea to put 
it down the drain :) The neighbors below probably wont appreciate it.
