Some more advise from one newbie to another:
1. Be prepared to only win the crappy lockers in the beginning.
2. If you get a shot at a decent looking unit, be prepared to get run up. Just pay the extra cost (as long as you can afford it) and don't make a big deal about getting run up. In some parts of the country you just have to do this to break into the game.
3. Do NOT get into bidding wars with regulars, especially your local whales.
4. Try to befriend as many regulars as possible, don't ask a lot of questions, but don't brag about your business acumen either. For example don't say "Yeah, I'm new to storage auctions, but i've been selling cars for fifteen years, and I got a lot of money, and I know how to make money, yada, yada, yada...
5. Go to many auctions, don't do or say anything stupid, and eventually you will meld into one of the regulars yourself and before long the old timers will stop running you up because they realize your here to stay or they start to like you and except you.
Just my experience.
