I use a Lee 10 pound bottom pour furnace. It works great for everything I cast except my 45-70. With a 6 cavity 425gr mold I have to fill the furnace all the time. So like you I'm now in the market for a pot and ladle.
With the single cavity mold you said you were looking at on another thread, a small deep cast iron pot that will hold about 10 pounds of lead will probably work well for you.
For ladles, I found the Lyman is the best for the money. It is slightly angled so it is easier on the wrist.
