I don't feel bad about getting a good deal, the camera was extremely rough and I doubt anyone else in the area would have restored it.
Funny, in your 2nd post you said and I quote: "the exterior was practically perfect". Since you are restoring (are you, I thought it was perfect) it it really does look like you went to the charity shop, haggled them out of some money then plan to sell the goods for profit. Just be careful not to sprain a shoulder trying to pat yourself on the back.
