Buffalo vs Cow Milk

[gmac]

I still have to have a successful mozzarella but my friend told me about one of his customers that is milking buffalo.  10% milk fat. 
So, my question is this: 
At $0.80 per liter for cows milk versus $3.00 per liter for buffalo (both raw unpasteurized).  Is it worth the extra?  I can buy a lot of cream for the difference to add to the milk.

Thanks

I have yet to find Buffaloes milk to purchase to make my cheese but I have purchased mozzarella di bufata just to try it as it is more traditional in Italy but even though I liked it, it is a stronger flavor and I didn't feel it was worth buying again for the price.
