@jaybird honest answer? It depends on the wife.
Hubby surprised me with a mixer, new knives and a cutting board. I was so happy I cried. Checker at the store asked if he was outfitting a new apartment. When hubby told him they were a gift for me, and we were not in a fight, the checker stood there in shock.
So. Simple answer: depends
@jaybird a good question might be, does your current vacuum suck and are you also going to get rid of it and find a new home for this one unless you have a special need for an additional suck machine? Cause I hear sharks are pretty good, but being clueless about the work being done may mean your friend should probably stick to diamonds or something.
