Is it improper to ask for tech manuals on forums?

I'm looking at getting a few broken/unused/no longer needed regs. I want to start working on them just as a side hobby. I can't go diving so I figured I'd try to learn something else that'd help me out in the future. Plus, the wife won't mind, as I can still watch Tanner too. :P

I'm looking on different sites and will post to see if anyone has old ones or broken ones they no longer need. Anyone here have any? I'll pay shipping.

Ohh and where would I get the parts? Do I get them through my LDS? Don't they get it for free? Would they charge me and get 100% profit? How does that work?

Thanks for any info. I'm sure I'll have plenty more questions to ask in the near future.
