FPGA development boards are indeed not cheap, as the chips themselves are expensive. But those of us who are in the field know some solutions. Indeed I'm working on designing a low cost FPGA board right now. Until mine is ready, a useful alternative is to reuse some mass marketed products that are cheap, like LED controllers boards. This one for example cost $11.50 and includes SDRAM and ethernet:
