Hi and welcome to the forum. Asking what the right amp is a very subjective question. You could ask 10 people and get 10 different answers. Peavey are quality amps and the Vypyr seems to be well liked. Of course he would like the footswitch, we (guys) love gadgets and gear.
What kind of music does he play? Does he also play with other people (and a drummer) ? I think the 75-watt would be a good choice, it will be loud enough. Are you buying from a local music store? If so, maybe the salesman can give you some good insight as well.
Personally, I like Vox VT30 or VT50 modeling amps that cost as much as the Peavey Vypyr. But again, this is a subjective question. Needless to say, if my wife bought me a Peavey Vypyr for my B-day, I would be a very happy man!
