Reply to Midi Keyboards

Right, I know this has been up here in the past as I used the search function, but I was to ask the wonderful people on DJTT what you would buy.

I currently use the Novation Launchpad with Ableton to put stuff together for production purposes, but have realised it's much better for playing out with aka as a controller, on top of that I need to be able to play chords and the likes, so was believeing of actually getting a midi keyboard instead which has pads and rotaries and of course keys.

so my question is, as a starter would you buy a 25 key or 49 key?

question 2 is out of the following models what would you say is my best bet, I can afford upto
