Has anyone here heard of or used a Firebox stove?

Here is a link to the website for those who dont know:

I am pretty interesting in getting one for my ultralight weight set up. I like how you can burn multiple fuels and how it folds into such a small compact size. I can see it being a bit inconvienent with how hot the steal will get and how long it may take to cool down when I am done using it but I am very interested in the size and versatility of it. It seems like a pretty amazing product.

So anyone here have any experiences or opinions on the Firebox before I make the purchase?

Those seem pricey for what they do, and I don't like to buy something that is relatively easy to make.  For example, here is a 3oz stove that takes no money only and little time to make:

I'm sure there are many other designs for these.  Try making one and see if it works well enough.  If it doesn't then you will have had a little fun and the commercial product will always be available.

Awesome link! Thank you.

However, I am interested in the stove I mentioned because of how flat it stores. I am trying to build a bag that has all of the essentials in the smallest lightest pack possible. I think I will spend a little time on Sunday trying to make that coffee stove, but I do not have room for it in my pack. Price is a bit steap which is why I wanted some opinions before I spend 60 bucks on 99cents of stainless steal that folds flat.
