For the smallest 45ACP I have, and know of, is the AMT Backup in 45ACP. I bought mine new in '94 or '95 (whenever they first came out) and only paid $365 for it. It may be difficult finding a used one, though. I can cup the Backup between my hands and hide it completely. After that, I'd go with a Colt Officer's ACP or clones. After that, I'd go for a tiny Glock.
