I do not own one, but have used them several times. They are decent consoles. Lots of engineers like to bash Mackies but I still think they are very good for the money, but these days that price tag should not be too high. Keep an eye on the used market. They can go for pretty cheap and last a long time pretty maintainance free.
You may also want to check out the 4 buss consoles like the 24x4, which is a pretty solid console. They are not the best consoles on the planet, but not the worst. I have done major lable work on them and the record company did not seem to mind.
