Its a good price if you're in the market for a 3D printer, but given the technology used (fused filament) I wouldn't recommend them for anything brewing / food etc. related. The parts will have small holes and imperfections, which make perfect sites for bugs. Good for taps and similar where its less of an issue. The home models of whatever brand all have issues so need patience and a fair input of time to produce decent models, plus an ability to design models in 3D int he 1st place, unless you're happy to be reliant on other people's published models. That seems to be true however much you spend. The days of true plug and play for 3D technology is still some way off.
That said, there is something truly amazing and magical about watching a carefully planned model come slowly to life before you eyes, layer by tiny layer
