I scrolled through this forum and couldn't really find what I was looking for (although I'm a notoriously bad searcher). Is there a thread or a link to general NES maintenance and repair?

I am in the process of hooking up all my old consoles once again. Both of my old two front loaders just blink or reset with all of my games. As a kid I saw people blow out the games quickly like a harmonica -- I tried that too but to no avail. I did read something about bending pins, but I'm not really sure what or how to do that.

The main reason I'm asking is I see quite a few top loaders on eBay right now. Would it be better to just buy one of those? They seem kind of high. If I could bend the pins and get mine working again I would do that, but I would probably buy a top loader before I tried installing a new set of pins.

Any help, links or advice from you guys would be appreciated.
