I have used a Stylus for several years now and have nothing bad to say. I love it. I really like the fact that I can assign any swith to any funcyion. I lso like that it is shift selectable so I can use any btand receiver, positive or negative shift. The card features are great too.
Here is an old link that really covers the features and small review as well:
