What should I get - help

So barb gave me a gift certificate to amazon for the 30 bucks. She and brandi helped me compile a few interesting things that amazon has for sale. I need some help deciding which one to get - or if you find something else more interesting on amazon for UNDER 30 bucks post a link in the comments. Whatever I end up getting I will write a little mini-review here on my site.

Here are the items - in no specific order or rank.

item one
item two
item three
item four
item five
item six (thanks brian)
