Are you looking for a regular machine, or an espresso machine?
Regular machines do nothing but evaporate water and condense it right after it. Your decision should be made on design and price only!
On espresso machines.....
Well, don't bother to buy one under 1000 euros!
Some German companies have nice design these days (Siemens, Porsche), but Italian are hard to beat at design.
As for the taste: Go for Saeco (that's subjective though)! Great design too.
