Choosing Granite Kitchen Countertop

Hello:

In researching I have found that some Granite (http://tanbrown.org) has a higher water absorption percentage than others.  Without going with the Absolute Black which I understand (http://maplered.com) has the least absorption rate, can you suggest others that are fairly good.  I am looking at the New Juparana Persa but am leery because I have read that the Juparana series is rather porous.  I am into low maintenance and (http://maplered.com) do not want to seal the Granite (http://tanbrown.org) every 4 - 6 months.
I have read about the lemon juice test but cannot bring myself to trying this when going through the supplier's yard.

Also, am I correct with my analogy that the rate of absorption in the different Granite (http://tanbrown.org) s can be compared to say, the rate a paper towel will absorb water as compared to the rate a terry towel will absorb water?

Thanks
