I've been using a Behringer UM100 Pedal ever since I started playing (2 years ago) and I'm happy with it. imo it's a perfect begginers distortion.
My rig:

Jackson JS30DKT Hardtail
Behringer UM100 Pedal
Peavy Blazer 158 amp.
Boss DS-1 is ok. It gets bad reviews because compared to most distortion pedals it sin't very good. But for the price and especially if you are a beginner it will certainly do the trick.
