Hi Aharon
I did play around with Nuendo many years ago - I have a friend who has had good results using it - it is MUCH MORE STABLE than the buggy Cubase and very rarely crashes the system. I must admit that I have not spent very much time with it in recent years - in fact I have not had much time to record anything - shame on me

, but recently another friend downloaded REAPER and turned me on to it.
Reaper is one of the best if not the best piece of recording software available and it is VERY cheap to purchase. You can download it for free - full working version, not crippleware

.
What I REALLY like about reaper (apart from the continuous upgrades and development process) is the very low use of the computer's CPU when running LOTS of VSTi and plugin effects. we are talking about four different effects per track and at least 8 tracks running on a Pentium 4 computer!!!
You can even record 8 tracks in real time with dsp effects on each track whilst recording with no crashes or lock ups.
Of course the recording will not have the effects on it but it is nice to record vocals with a nice reverb you can here through the monitors when recording.
I would seriously suggest you give Reaper a try first - it is a very easy and intuitive piece of software to set up and use.
The guy who designed and continues to develop it is a Genius (Justin Frankel). He was responsible for Winamp 5.
