Yes they are generic.
I can't recommend one, best to go in a shop and get a feel for one you like based on what you can afford and to suit your needs.
Just remember turn off Vibration Reduction (VR) on the lens when you use a tripod. And either use a remote or timed shutter release will help too.
All the info you need is here.
