I've been searching through Amazon for a few minutes, looking at aquariums and supplies, things like that. I just wanted to post some awesome deals for people like me that are on a very tight budget.
I am not claiming that any of these items are top notch. They are cheaper and have good reviews. I will state the ones that I use myself. Anything else I just found and thought others might be interested in them. If you have experience with any of these products, please leave your feedback.

Much better than the $30 I paid for mine at Petsmart. If you're using strips it'll eventually pay for itself in the long run, since you aren't having to buy strips all the time. :)
