I'm looking to get a MIDI controller to use it for editing in Lightroom, after researching for an hour I think the Behringer X-Mini Midi controller. It's affordable and offers a fair amount of knobs/buttons. However I'm afraid that it might not be enough. The 16 knobs (8 with 2 layouts) seem fair, but I think I could use more than 16 buttons. Does anyone know a similar controller (in size and price) with some more normal buttons?

If not, I'll just order this one, but I just want to make sure there isn't a better alternative I might have missed.
