I have been using this large (4" - 5" mouth?) graphite crucible that I ordered from Amazon. It has worked perfectly so far, after at least 11 pours, with no sign of degrading:

If your budget is pretty firm, there are smaller and cheaper, versions that are similar:

I got mine from PMC Supplies at Amazon. Budget Casting Supply has very good ones as well. They're a bit more costly, but they're also a bit higher quality.
I hear ya - I was trying with just a small charcoal grill and insulating a bit, then heating directly with a small propane torch. It was inefficient, ineffective, and likely more dangerous as I was closer to the fumes.
This is the one I have been using - and very happy with it. I did make some empty camping propane bottles into ones as well but ended up burning through them on the bottom.
$15?! link? if you're paying only $15 for graphite you'll be getting something slightly bigger than a thimble. this is the one I got. $36. the opening is big enough to melt cans. I wish I went bigger. next time.
