When you install the Altera tools, it automatically installs NIOS and gcc. I assume there are no restrictions for private use, but you may have to send $ if you make a commercial product. That remains to be checked.
I have not used NIOS either.

I'm not familiar with them and don't know how much they cost. Until now I have developed on Xilinx 50Kgates FPGA and 128 cells CPLD with the Xilinx's free tools.
