Very very happy with my bubble magus so far. It's close enough in cost to the drews doser and even slightly cheaper if you add in the extras you need with the drews doser setup. Additionally, bubble magus has 3 rollers vs 2 for the brs setup.
For containers I highly recommend lock & lock 1 gallon food storage tubs. I'll try to post a pic of my setup, but they are a convenient size and shape, and there are lots of choices for shapes and sizes if the 1g ones aren't ideal for you. They are also under $5 each at kamei.
I do have one slight gripe about the bm. It's chintzy power plug kept falling out of my power strip and had to be zip tied in place. However this also led to the discovery that my bm remembers my settings through power interruptions, which is nice. It's also fairly easy to set up in spite of instructions best gibberish being in written happily flowers sunshining to flow pump adjust.
