Very much more important to choose wisely the audio interface you'll be needing, if you're at all serious in your desire to record stuff. For a modest outlay (second-hand is fine, if guided in your choice...), the ease and quality of your recordings will be ample reward. Ask for advice if/when you go down that route, but you'll thank us all for it.
As for Cakewalk v Reaper ... I tried Cakewalk a short while back, but I have already my way of thinking modelled on Reaper, and could get nowhere with it. I must admit to finding Reaper very easy to work with for simple things, which is what I do, but able to extend much, much further if required. Simple things are simple with pretty much any model software, I'd say, but not all are capable of more than that, once the initial 'honeymoon' is over.
