Looking for Used, Cheap Superhero Gear

Hey guys, boyfriend and I are new into the whole superhero fetish scene. Looking to buy some of your old gear if you aren't using them? Really like The Flash, Superman/Superboy, Power Ranger, Green Lantern, etc. Open to whatever you got, also willing to discuss price. We're both around 6'1 with a 33 waist and 36 waist. Even if it's a bit smaller it'll work for us. Let me know guys!
