Query: don't buy

Bought it last week in the "Target" store because of the price and many positive reviews here. Came back home, unpacked it and found the water container broken. Went back to the "Target", they replaced it with another one. Came back home, made a very good cup of espresso each morning for 5 days, but noticed that the pump for frothing worked poorly - today after five days only since I bought this machine the pump died completely, the steam was built up inside but could not be released by turning the release button (yes, I cleaned everything after each use, I have been using espresso machines before). I am on my way now to return it to the store. I am considering purchasing a better quality machine once I can afford it.
