Adding to my collection

So far I have about 5 cameras in my collection. All of which I absolutely LOVE yet I am still looking to add to my collection. For my collection I don't mind if it's in working condition or not, as long as it's not completely destroyed. I was just wondering if anyone had any suggestions on where I could get these for a cheap price, or for free. I will be accepting donations but I am totally NOT asking at all don't think that that would happen anyways (just open to all suggestions.)  Here are some types that i'm interested in. ( <3) See yoou
