IceSugarPro (with its breakout board) is quite a nice board if you want something pre-assembled. Same FPGA as this new board (so also supported by the Open Source toolchain), same size SDRAM, HDMI out but PMODs for everything else.
I really like the look of this new board, though - I definitely want to get my hands on one. (I also have a Tang Nano 20K but don't like it all that much.)
I have the icesugar pro as well. I like the SODIMM form factor because it works well on a cheap four-layer carrier board and it exposes a lot of IO, which is what I want when I'm doing stuff with FPGAs.
