The regulal LVDS pins aren't fast enough for SATA. You need an FPGA with transceivers for that, such as an Arria, or one of the Cyclone/Statix GX variants. Have a look here (http://www.altera.com/technology/high_speed/protocols/sata-sas/pro-sata-sas.html).

As for an inexpensive starter board with pins, you can have a look at the bemicro (http://www.arroweurope.com/markets-solutions/solutions/bemicro/bemicro.html) (careful, IIRC this board uses a special kind of RAM that requires a licensed core) or the Cyclone IV de0-nano (http://www.terasic.com.tw/cgi-bin/page/archive.pl?no=593) board. I'd recommend the DE0-Nano. It has 72 I/O pins from what I can read.
