I have the Princess Auto portable band saw which appears to be the same. It's not always in stock but when it is it always seems to be on sale for $100 or so. The sound it makes doesn't inspire confidence but it's got the job done quite nicely for the 5 or 6 times I've used it. These are real handy when you need to take the saw to the metal vs. the metal to the saw.
I like mine for home use. I think pro would get sick of the tensioning mechanism as the rubber on the wheels is kinda soft and allows the blade to slip. Far better than a hacksaw when you actually purchase a metal cutting blade. The one in the box is for wood.
There was a pretty good review on that band saw on shopfloortalk.com a few years ago. talked about a few minor mods too. I forgot my log in so I couldn't do a search to find it.
