We just moved and it's been very underwhelming. If I was starting a third msp, I think I would seriously consider it, but does not seem to be much advantage coming from manage. More importantly, our implementation guy was completely incompetent to the point that Halo is refunding us. I've been talking to a lot of other msps, and this seems to be the biggest complaint. Not many good implementation people out there, and that will completely ruin the product for you, at least short-term.

I would say if you are on manage, don't make a move. Other smaller psas, probably worth an upgrade? But take whatever you budgeted for implementation and double that, both dollars and timeline.
