Hi Christian_1
This Axiom 61 http://www.m-audio.com/products/en_us/Axiom61.html is a very good entry level model, as most of the controls can be programmed to do whatever you want. It also comes with Ableton Lite software which will allow you to get started producing music straight away. (Including controlling VSTi)
As with most things you get what you pay for, but if you’re not sure, it’s a good starter.
You can do a search for your local distributor from the site, or use Google Product Search to find the best deal.
Hope this helps

Bill
