BRS dosing pumps are commonly used and fairly priced and reliable. They retail for $70-80/each, but of course you can buy a "used" one for cheaper

The BRS and Drew's pumps are really great if you have a controller. If you don't, I really like the Bubble Magus 3-head doser. For $299 you can't go wrong and it is super easy to program. Both the BRS pumps and the Bubble Magus all have readily available replacement heads and tubing very inexpensively.

If you want the best on the market - go with a Vertex Libra with the stepper servos which goes for around $600-$650.

Don't buy one called 'Babyfish' unless you want an inexpensive doser of very questionable quality. I got one in a group buy cheap, just to try out. There was a disconnected electronic plug inside when I got it. The timer loses 5 minutes every hour and when it says it will dose 50ml it only dosed 32. So all round inaccurate and poorly made... but it does dose. The question is, for how long?

Best on the market in my opinion is the Spectrapure LiterMeter III. They have been building this pump for over two decades and they are bulletproof.
Thousands in use.
