Tekton tools on Amazon seem to be very nice for the price. I bought a couple of their ratchets and pliers and I really like them. I plan on buying more of their stuff to keep in my vehicle emergency tool kits.
I would recommend buying a Husky nylon tool bag, and fill it with a metric ratchet set, metric combo wrenches, a couple of pliers and a screwdriver set.
This would get you started and could be done for <$100.
