Your gonna get suggestions for these http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER

They can be found at some WalMarts and on their website they have a list of retailers, maybe they have one near you. I have had one before but it failed after just a few months so I do not like suggesting it to he honest.

I now use Herpstats and have a 1, 2, and 4. They are awesome. The Herpstat 1 is not to expensive and will last you a long time. They also have a Basic which is cheaper. Check out the link to compare the models. I believe in doing it right the first time, that may cost more up front but saves more in the long run.
