Please define "good pay" and "good benefits". For me, the "pay" part would have to be substantial. The tangible benefits I currently have are average. The flextime is fantastic though (I work remotely at least once or twice a week and there is a very flexible notion of "business hours").
Everything is relative. I think its hard to generalize. There are lots of startups that are much more lenient with remote work, and many that embrace the basecamp-style company values. In general, if you are not in SV or maybe NYC, big open source job markets, you tend to hit a pay wall pretty quickly.
It is much harder for me to find a startup that pays as well as a more traditional IT shop would pay me. I can find a 130-140k job in .NET here in South Florida with relative ease. For open source, there are maybe a handful of companies willing to pay that kind of money. In general, these enterprise places will offer very good benefits (vacation/401k w contribution/paid healthcare) and the work is not hard in comparison.
At startups, its just spottier. Last place I worked paid me same as before but didn't contribute towards my healthcare.. That was an extra $1300 / month that had to come out of my paycheck and an expensive lesson.
(Having only been at one place thus far my opinion may be different)
I've yet to come across someone who has been "happy" with their benefits package. I don't even take advantage of mine because it's such a large chunk for a single person, and yields no incentives - these I would likely consider tangible benefits (aside from the obvious). I could see it being nice if I had a family though, but most people I've spoken to use their significant others benefits package.
The one thing I hope to always have wherever I work is flexible working hours. I very much dislike the stigma of "oh you're not first into the office!". Maybe it's just me though who has ran into this.
