I was so excited to hear about the RDB, until I saw the price tag on the thing. IMo, either the Tavor or the RDB (or both) are priced way too high. With them being within a few hundred bucks of each other, it makes it hard to justify buying the RDB. Too bad, because if they had priced it right, they would have sold a million of the damn things.
I find the Tavor a bit too heavy and bulky (just imo). It's the Kim Kardashian of the 5.56 world (too much bulky weight in the azz...like there's double the material there that there needs to be

). IMo, still the best option out there, I guess.
T-97 looks like a good deal, but only when it's priced around $600.
Canadian offerings of bullpups all seem to be pretty inaccurate though; at least that's my own perception of them.
