£250 3D Printer offer

[ffutures]

Does this look like a good deal, and a reasonable printer? Seems cheap, but I have a feeling they aren't mentioning snags. Or has the technology really come along a lot recently? Looks like the filament costs £33 a roll but they don't say how much you get and how big a volume it will make.

There are two more expensive models, one of them incorporating a 3D scanner, but it's more than double the price.
