I’ve recently become fascinated with the concept of the alcohol stove. A small, light clean-burning stove sounds about ideal for solo-camping/BOB detail. 
I have been doing some research on these little devices–both DIY and commercial versions, including the “cottage-industry” types like Mini Bull Designs (they ARE made from recycled cans, after all!)–and wanted to see if any of you have any experience with this type of stove (making and/or using).
At this point, I’m particularly interested in the MBD IsoFly (for it’s versatility) and the Vargo Titanium Decagon (for it’s simplicity), but I’m open to other suggestions. I understand the limitations of alcohol stoves when it comes to burn-time, boil-time, and cooking limitations (my lack of kitchen skills notwithstanding); at this point I’m just looking for user feedback, insight, and perhaps some alternatives I haven’t considered.
Thanks in advance for any info!
