Here are 3 protein powders I have found over the years that I like......
Nature's Plus Spiru-tein
Solaray Soytein
Natural Factors SlimStyle (just basic chocolate, strawberry & vanilla flavors but very good as a thick shake or pudding on it's own)
All non-gritty. I discovered Spiru-tein after I had been using both the Solaray & Natural Factors brands for a number of years. Even though I like them all the Spiru-tein has become my favorite. I love smoothies and with or without fruit this line of protein shakes has over 20 flavors to choose from.
I buy mine from Super Supplements. They carry some flavors in-store but prices are cheaper on-line and of course you have more variety to choose from. I order on-line and order several flavors at a time because over $49 you get free shipping and there is no tax because it is a food item. Being in the Seattle area (where SS is based) my shakes are usually on my doorstep next day.
