Hello I would like to buy a tattoo gun?

I have a power supply. I was thinking for my birthday Id spend a couple hundred on a gun, then I will have a bit for everything else. I'm not interested in a tattoo kit. Just if anyone knows of a machine between 100-and 200$ or websites I should check out I am looking for that information. Right now the machines I'm looking at are from tattoosoul.com . I'm well aware I can't get a good gun for this price. However i am just trying to get a decent enough gun to start practicing on some line work and shading on my leg and my friend also donated his leg to the cause. I've messed with myself a bit with a homemade machine before, the sucky thing is I am addicted into submission and don't want to be ruining my skin with a gun I made myself. So yea if there are any artist or people familiar with the art that have any good recommendations for me I would highly appreciate them.
