I'll just add a couple of thoughts.
I use the 24.8. I generally like it and have done some good stuff on it (I think). In fact, my partner and I felt it was such a value that when we were investigating a second console for our live recording setup, we chose a 32.8.
The eq onboard works better in a subtractive nature...I generally don't use it for additive EQ. Routing options are really quite good for the money.
It can be used for summing but you'll likely get a better image through a dedicated summing box, but it's not bad. I did notice that when the mixes went to mastering, they ended up a bit wider on the mastering console without any stereo wideners added. (I really dislike wideners)
In sum, I think it's hard to argue that it isn't a value at the prices they can be had at. Not sure what your budget is...but a summing box and good outboard eqs will likely cost an arm and a leg for a marginal benefit.
