I use CP pistons. I have a profile on them but they are not cheap. So no I do not know of any thing else. There was a guy talking about honda rods or something a while back but that is not my thing. You could also have the stock pistons machined for lower compression. But I would go with forged pistons if you are planning on a lot of boost. But you could gap the rings and if your tune was good make 500+hp on stock pistons. Kind of depends on your goals. But everything behind the engine will be toast in short order.
