if money is an issue, the DS-1 can do what the DS-2 can, but if you can afford the DS-2, buy it. I rarely see the DS-2 for sale used, and that is how I buy most of my gear, but I would suggest looking for a used DS-2. It is a boss pedal, which means it is virtually indestructible, so don't worry about damage.
