I was thinking about picking up there 2 part Doser. I've been using the B-Ionic 2 Part and was also going to switch over to the BRS stuff.

I take it I need 2 of them correct? 1 for Calcium and another for Alkalinity? And what would be the advantages over say the Litermeter 3 to this? Would I have to buy another remote pump for the Litermeter to be able to do both?

I don't have any experience with the Litermeter product. I bought three of "Drew's Dosers" which are the 1.6ml version of the pump you linked. I went ahead and bought three so I can also dose Magnesium. Once dialed in, the system is pretty much set it and forget it...
Here is mine, using 2.5G reservoir tanks I bought at Wal-Mart.

So are you happy over all with the Drews Dosers? Those are also an option I've been researching the litermeter the last few days and have seen a lot of stories where people hit the wrong button and end up dosing 2 gallons of alk in 30 sec. So thats why I was looking at the BRS Doser (Cause there are no buttons and a bit cheaper)

I have used the BRS Drews dosers for a couple of months now. The first task is manually dose to get your tank's ALK, CA and MG parameters exactly where you want them.
Then, testing every day, you set your controller's timers on ALK until dKH stays where you want it. The dosing is compensating for the ALK being taken up by your tank...
After ALK is steady, Randy Holmes-Farley recommends that you dose equal amounts of CA. In other words, if I dose ALK for two hours a day, I dose CA for the same amount of time. Then I test the CA to verify that it is also steady. I had to increase my CA by dosing 15 minutes longer each day to maintain it at 450.
Finally I started dosing MG at about half the time daily that I dose the previous supplements. I continued to test daily, adjusting the dosing time until the MG remained close to 1350.

With that regimine,
how often are you having to replinish each of the 2.5 gal alk/calc/mag containers?

A full reservoir lasts several weeks... I haven't marked it on a calendar, but will make a note the next time I mix up 2 gallons to top off the containers...
