I'd second that, and add that pricing is particularly competitive if you're 26 or under (which I realize the OP probably isn't if s/he has a family of 4, but it might apply to others).
This is one of the more startup-friendly features of living in MA as opposed to the Valley.
Yeah, I'm a bit surprised that startups that haven't been able to get recent angel funding in CA haven't moved to MA just for this reason. (Again, all else being equal, no family restrictions, etc.)
Actually, I think they do... at least, comparing personal income tax rates (the factor most likely to matter to a new startup), MA does reasonably well: a flat 5.3%, as compared to CA's 1-9% (with the highest rate kicking in around $50K or so).
Obviously personal income tax isn't the only one in town, but it's not significantly worse in MA than elsewhere.
