How many channels do you want to feed into it and how many busses do you require?

Do you need inert points for higher quality vocal preamps, do you want to patch an effects processor through it ?

If you want to use it for gigging you will need an attentional power amp and speakers.

However if you want to use it for recording and dont intend to use more than two channels at a time than you may want to think about a nice preamp and break out box to feed into your laptop rather than a desk.
