Reputation is always good to start off with and if you dont have that much stuff to store, many places do have cheap plans.

What you need to look out for is below:
- cheapy place that offers what you think is good to what really isnt
- cheapy places that rock and these are the ones you want

I think if you can find a couple and post the specs on what they offer many here wound be willing to help you narrow it down.

What type of space/bw/etc are you using now?
