Lacehim RM, just think of it as a mark 1. Somewhere to learn and develop in to the mark 2. Keep your eye our on ebay/gumtree, garage sales and the local classifieds. A s/s pot will turn up cheap.
Brett_H I had a BBQ roaster and it did work brilliantly. Very messy and large but the BBQ was a hooded one from eBay for $50 second hand so you may find it the cheaper option. It also gives you the option for a larger drum for increased batch sizes. Only drawback of mine was unloading manually with gloves. That's why it didn't suit me in the end.
