I did a search and can't find it either - then went to Dremel, and if you choose "USA" it doesn't appear, choose Australia (and from other sources, presumably UK) you get the torch and a cool glue gun. In fact, tho Dremel is a US company I think, the US version is not as nice as the AUS version (similar, but seems easier to nav and more products!)
My Dad got me my first Dremel a long time back, about 33 years - still going strong, but I did buy a new one anyway.
I think any compact torch would be good, they sell them in hardware stores, and I'd think MicroMark and Brookstone would have them...
