We brought all new stuff, but we didn't spend overly huge amounts of money...We got everything from the one shop and they did a bit of a discount for us because we were buying in 'bulk' so to speak. I'll try to remember approx costs:
Matching cot and change table and cot mattress - $800ish (it was on special)
Bassinet - $100 (also on special)
Change mat, mattress protectors (bassinet and cot) - not much, maybe $100ish?

We already had shelves in the built in cupboard in the room so we didn't need a chest of drawers. We brought one of those 'cube shelves' things from ikea which didn't cost much to use to put toys on.

We purchased sheets from target, so that was also minimal costl
