If you decide to get a Dyna, you can start off with a cheap hand torch for a month or two to decide if you like it enough to spend on a more expensive induction heater. The Dynacup IH is 55-65$ USD and the inspire wand is often on sale for 90-100$usd on dynavap site. I share your concerns about fire and dont like filling butane so I went for the wand as first upgrade.
Its a little late but I wanted to tell you that I love this! King Duncan is thankful for the nice poetry :)
You shall be spared from toiling in the catnip fields when he forces the world to observe his omnipotence.
