If you fancy winning some money then there is a great competition for bloggers on http://www.waterproofmemoboards.com. There are 3 prizes - $25, $10 and $5 and in order to win you just have to write an article on your blog of more than 100 words including a couple of links - waterproof memo board and memo board. If you have multiple blogs you can enter multiple times - one entry per blog. You just have to send your link using the contact page and you will be entered in the draw. For details go to the contest page.
What I think is this and I am not saying it to bring you down anything. People will enter if you put the prizes higher because I can offer a review on my site of 100 words and get $15-20 for it.
