I have a Hantek DSO-2250 USB scope kit as here:
with a set of two extra 150hz probes for sale for $150 (includes shipping to the lower 48 states only). This has only been used for a matter of hours over the course of a few days so is like new.
I have some power supplies from reviews available too...an Antec HCP-1200, Antec NeoECO 520C and an OCZ Fatal1ty 400W. All were review tested and opened for photography and no use since. If anyone is interested in any of these and wants details lemme know and can probably work out a good deal.
EDIT: scope and power supplies are sold
