As an additional note, the type of keys that are the least loud are cherry red, cherry black, and cherry brown. My second picks for you if you end up not going with the Razer keyboard would be:
Corsair K60 - Cherry Red ($95)
Steelseries 6GV2 - Cherry Black but no macro buttons ($90)
Thermaltake G1 - Cherry Black but no macro buttons ($100)
Here's an order of the switches from tactile (left) to smooth (right):
BLUE -> BROWN -> BLACK -> RED
Blue is too clicky for you and may disturb your family, red is very good for gaming but feels empty to type on, black is like red, just with more resistance so there's less of a chance to mistype, and brown is like red (45g actuation) but also has a little bump on it when you type, which is why I recommend it.
There aren't too many brown cherry boards out there that are in your price range, one that I can name that's really good is the DasKeyboard Silent ($130), but it lacks both backlit keys and programmable keys.
It's relatively difficult to find a good mechanical keyboard with macro keys, there are only a select few like the K60/90 and the Blackwidow that come with it. It's just as difficult to find one that has both back lit keys and macro keys, such as the Blackwidow Ultimate or K90. Some of the K60/90 ergonomics I don't agree with, like media buttons, having 18 macro buttons, or the fact that not all of the K60/90 keys are actually mechanical. What they did there is they only set the most used keys (like the qwerty key area) to have mechanical switches, they didn't actually put mechanical switches under delete key section, the f-row, or the macro keys (under macro keys to have them lower down for ergonomics). They did do somethings right like use laser etched keys, space apart their macro keys, and include a very good wrist rest for you though so decide for yourself if those benefits outweigh the cons.
I prefer the Blackwidow because it retains the original keyboard layout and size, it has that matte finish, has mechanical switches throughout the board, and uses just enough macro buttons (5) for anything you could need. Some cons of the Blackwidow are that the ergonomics of the macro keys make it hard to ground your left hand where it should be, resulting in some slip ups in the beginning and having your left hand hit the wrong thing. I outgrew this con in a couple weeks from purchase so it shouldn't be a big deal. Another con is that it doesn't come with a wrist rest, which as you stated before isn't that much of an issue. Keep in mind the Blackwidow is also cheaper by about $15.
When it comes down to it though, every keyboard has its own pros/cons that you need to weed through to find which one suits your needs the most. Everything we're talking about is subjective and comes down to the person's own opinions and needs.
Hope this helped
