Which configuration to choose?

[Nordsee]

Hi everybody.

Recently I had finaly decided to by some new hardware+software for my home studio.

At the moment I have several possiblilities, that are approximately within the same price range:

1. Digidesign MBox-2 HW + Pro Tools LE 7 SW
2. M-Audio Mobile Pre USB HW + Pro Tools M-Powered 7 SW
3. M-Audio Mobile Pre USB HW + Steinberg Cubase SL 3 SW

My basic requirements to the system are
- Professional sound quality
- Excelent MIDI and Automation editing capabilities
- Reliable Virtual Instrument support
- Mobility
- Overal system stablity

Most of the time I'm working with MIDI and Virtual Instruments (I'm doing -1 records for which vocals are usually recorded at professinal studio).

Entire system should be mobile since I travel alot all over the Globe and often whant my music stuff to be with me.

Which of above listed configs are more suitable for my neeeds? Or probably there are other options? (I have a buget up to 600EUR).

Thanx.
