You will be much happier with a Mark2 unit. They are a better unit all-around. They have better features and fewer hardware bugs. There is less of a chance of having ground loop noise on the line-level outputs of a Mark2 for example. It also has more RAM.

The Rio Car (Mark2a) is even better, as it has even more RAM and some minor hardware improvements (diode in the ignition circuit, if I recall correctly, for example).
