Level 2 streaming APIs

Looking to get streaming level 2 quotes, possibly the order book? Anyone have any luck with this? I'm using Tradier right now which I like but their stream quotes is basically just when a bid or ask gets changed so the underlying quote. I would love to know how to get the whole order book, or at least similar to how platforms show their level 2.
 
R|Api is the best choice. Simple, stable, fast. At the end of february 2018, thay promised MBO (level3) data will be available. IQFeed also is very good, but a little more expensive, and one also has to be familiar with winsock.
If you need institutional quality data, QuantHouse, dxFeed..
