I tried searching for it, and didn't find anything specific. Forgive me if I missed it.

My question is like the subject says. What should I not buy used? (excluding personal hygiene gear for obvious reasons) And probably another good question is as a newbie what should a buy used as I'll be learning what I like?

I need to buy gear for my wife, and a few items for myself since most of my gear is old and or very heavy, and my lovely wife has nothing. I would not rather break the bank, and I know I don't need every little thing. But as I've been researching important items like tents, packs, sleeping bags, outer clothing and other gear it starts to add up rather quickly.

Thanks for the help!
