Has anyone tried hosting their own site as a private reseller? Is it worth the investment?

I would say the break even is about 5 sites if you have more than that it is probably worth the money to do it yourself.

We have some at hostgator the problem is that you have to do the servicing on the accounts and we have found it is not worth the money you can charge in this commodity market

I would not bother it is a commodity service much of it is driven by costs and unless you are already established the cost of marketing will drive down your margins considerably

Thanks for your comments
