Best place to buy a cellphone? (need help)

Hey guys

I recently started looking for a new cellphone, one with mp3 player
capabilities. The Sony Ericsson W series came to my liking but none on the
carries in city offer them (Ottawa). So my question is if you guys have any
recommendations on where to get a reasonably priced cellphone online? or
even any stores in the upper New York area or Mtl/Toronto? ( I really don't
want to get caught up in the cell scams going around)

Thx for the help
