If you are going to go with a whole house surge protector, I strongly suggest you look into the Environmental Potentials EP 2050. It will run you a little more than your budget, but it is more than a simple surge protector. It will also send the noise from all of the houses that are on the same transformer back down the neutral and isolate your house from them. I use one and like what it does. Do a search to get more info on this great product.
Good luck,
