You COULD go for that model 1200, its cheap, but the head and GPH certainly is nothing to write home about, other more mainstream pumps have it beat. Also, thats quite a bit more wattage than many more powerful pumps, so if your rad is single then it may be a concern. If you arent willing to spend more than 30 dollars, you would probably be better off with a L20, or a Via Aqua 1300. If you are ok with spending in the $50 range... then you could do much, much better than the "1200 model."
