Reply to Midi Keyboard for beginner

i will start messing with production and i am getting NI Maschine mk2
i want also to add a midi keyboard to try to create some melodies and generally to control virtual synths easier than using maschine's pads

i am not a piano player,i am novice and my budget is limited so i decided to start with something cheap and give it a try,i dont want to buy something that would be overkill but neither something that i will want to upgrade it soon

i was believeing about 49 keys but price for 61 keys is similar for the entry models,i have much space on my desk and maybe later i will try to learn the basics and i will be "missing" that one more octave,so i believe 61 keys will be a better choice than 49

also another option was to choose a keyboard bundled with ableton live lite so i have the opportunity to try it and if i like it to use it as my daw

about knobs/sliders/pads i would like some knobs/sliders for ableton but dont care about pads because i will have maschine's pads

as a conclusion i ended up to M-audio Oxygen 61 3d gen. and Alesis QX61 but couldn't find any stores near me to check them,so i can compare them only from their speqs

-Alesis has midi in/out and ac power while M-audio is only usb powered
-M-audio has 9 sliders and 9 buttons under them while alesis has 8 sliders and no buttons under the sliders,does it counts when controlling ableton with a midi keyboard in addition to Maschine?
-in this price range quality is low,in some reviews i saw the upper plastic section of Alesis moving little bit up/down when you push it but i read some better comments for its keys than Oxygen's
-both of them don't have aftertouch but i dont know if i would take advantage of it and the cheapest keyboard with aftertouch is much more expensive

what is your opinion?go for one of them?which would you suggest?save money and go for something better (with aftertouch)?
