Questions on Wavemakers

Well I have had my tank up and running for a little over a year now. I am interested in buying a wave maker to increase the current or flow of the water. I currently have a Hydor powerhead that is rated 425 gph. I have a 40 gallon breeder tank and want to give it that reef like motion in the water. Ive done a little research on pulsing wave makers. I am just wondering what would be a good wave maker for my size tank and what is a cheaper, but good one? I don't mind spending some money but not looking to spend a lot of money on this. The powerhead I have in there now works alright. Although I would like more flow and to have the real ocean like current. Please help me! Thanks in advance
