Wine tour operators in California

[DJOblong]

This may be a LITTLE OT but can anyone recommend a wine tour operator for the Napa/Sonoma area that does a good yet not ludicrously expensive private tour or semi-priavte (share with other groups) tour of the Napa or Sonoma area? I am looking for good "ins" with vineyards of a high standard, not your typical mondavis, hess, opus one, blah blah blah. E.g. vineyards that would typically need invitations if you were visiting them indiviudally.

Thanks!

Here's one that might fill the bill: Beau Wine Tours.

You could save $$ by calling some of the smaller wineries and making appointments yourself, unless the limo is a must. If you'd like to do the self-directed route, I could recommend some of the smaller, boutique wineries that accept guests.
