Napa/Sonoma wine clubs with low shipment commitments and good QPR (similar to Robert Keenan)?

I'm currently a member of Robert Keenan's wine club and really enjoy it. I'm on their 2-shipments-a-year tier, and I think their QPR is excellent.

I'm looking for other Napa/Sonoma wineries with similar clubs: low shipment requirements (ideally 1-2/year, not the standard 4 shipments per year) and good QPR. I live alone with limited storage space, and I'd love to also branch out and try other wineries without overcommitting. Some other wineries whose wine I enjoy require me to commit to way too many shipments and/or too many bottles per shipment.

Any recommendations? Bonus points if the wine style is similar to Keenan's (I lean toward Bordeaux-style blends and Cabernet).

Thanks!
