Reply to Looking for some advice on MIDI Keyboard Controllers..

Hi,
I'm new to this community and this is my first post.

I'm a beginner in electronic music production. I use Ableton. I go to a music school to learn production where I was introduced to a Novation Launchkey 49, looked pretty good to me. I'm unaware of its competitive products, my teacher recommends it to me too and I've a gut feeling that it could be a decent buy.
The reason I've posted this post is to know what are the other products of this type, and how each could offer something different?
