I have a Lee 10# bottom pour and a Saeco 20# bottom pour, both do the job. The Lee has a habbit of leaking at the spout which can be an anoyance. The Saeco doesn't leak as much and has a wider mouth that allows for larger ingets to be melted. Both are old pots but still going strong. The Saeco also has more room under it, so I can cast with my hollow base molds, the smaller Lee pot does not have enough room.

Get a 20# pot, if you cast much it will be worth the extra cost.
