I love my Blackbird, there's only one other brand board with doubleshot keycaps that has backlighting and this one certainly looks better. The only negatives I have discovered is some strange incompatibility with my chipset at home z87 asus hero (works on all 7 other computers I have test it perfectly fine, the work around was to plug it in through a hub). So if you have that particular board you might look into the deck keyboard instead.
Only other complaint is that I don't like the location for the lock-light indicators. When they are above the Ins/Home/PgUp they can be hard to see. The backlighting in red or blue should be fine though with either keyboard. I think the issue people have with blue LED's has more to do with the quality of the keyboard itself. You want good current regulation for LED's but some places probably just use resistors or other poor forms of regulation.
if good keycaps are not important to you then I would look into getting the CM Storm Quickfire TK.
Also, nraymond the information above isn't correct the blackbird does not have PBT keycaps, they are doubleshot ABS. The doubleshot abs are still also nicer than regular painted ABS caps though! Deck is currently the only option for doubleshot PBT keycaps with backlighting, but IMO they didn't look as good or as uniform in the pictures, so it is a trade off I guess. I also love my blackbird, especially since it is a lot cheaper than the deck with it's funky fonts.
Another positive is that the blackbird is made in Taiwan, rather than china, although made in china does not indicate it is a bad board in itself it's not something I look for when purchasing, the QC for boards made in Taiwan seem to have less variance.
