300 about the right price.  Except for a couple providers on my MUST SEE list, I stopped going over 300 a couple of years ago.  

There is only a couple of provider that I think are worth an extra $.5 and that is mostly because I am fond of them.

The only provider in the entire country in my long memory that is worth well over the $$$ and the only provider that is a solid 10 IMHO is Gina Rollins.  Pricey?  Depends on how you look at it.  Yeah, $$$$$$ is pricey but, the service is beyond belief and she once stayed longer than you can guess to get a second load from me.  The hourly rate that day was VERY reasonable.  Gina's pricing system is interesting; it seems to be based on something other than an hourly rate - not sure what it is other than to make sure you are happy.  Maybe that is why she is a 10 .... IMO.
