Nice - I can see a lot going for it! Doesn't take up much space. Inexpensive. Looks like it works pretty well (much better I'd imagine than holding the portable in your hands, or using a hacksaw.)

I was wondering if there are any issues with the design of the blade traveling away from the pivot point instead of towards it, however? It seems like on tall workpieces, the saw blade would tend to pull the work upwards off the table because of blade angle / direction of blade travel. Also, it seems like since the fence is moving with the saw arm, it would not be useful for a part clamped down on a table. Since the fence would move relative to the workpiece. I wonder if there would be much value in moving the fence off the portable saw arm, down onto the table.

Main value I'd have with a setup like this (in my limited space shop) is how little space it takes compared to a traditional 4x6 horizontal bandsaw setup. I'm envisioning something with a light enough frame (perhaps constructed out of rigid&lightweight aluminum tubing instead of steel for the frame...) so that it could easily be lifted up onto a shelf for storage when not in use. Plus, you gotta love how inexpensively bimetal portable bandsaw blades can be purchased for!

It seems like these portable bandsaws have pretty decent cutting size capacity (width x height), too.
