A REALLY, REALLY cheap way to try casting, is to use Lee equipment.
They used to make a stamped steel lead melting pot about 4" diameter and 4" high, that will hold about 4 pounds of lead - one can likely be found as old stock in a gunshop or at a gun show for about $10.00 (or use the cheapest, smallest diameter but thick steel 'Goodwill Store' pot you can find, emphasis on small diameter).
A Lee lead stirrer/ladle is currently about $7.00 - $10.00 new.
A Lee bullet mould is likely about $30.00 in Canada now (get a tumble-lube type so you can skip the sizing bit).
Every real Canadian household has a Coleman type white gas/propane camping stove lying around someplace.
Scrounge/buy a small quantity of lead.
Read the instructions that come with the mould.
Put everything on your outside picnic table/work bench, fire up the stove and have at it (DO NOT do this in the kitchen).
If you enjoy casting, that's all she wrote, you are hooked for life and will THEN spend lots of money buying various different moulds, electric furnaces, sizer/lubricators etc. etc., with no end in sight as you experiment more.
If you don't enjoy casting, then you are only out about $50.00 - $60.00 and can recoup some of that by selling the stuff on the EE.
