I just posted on the 2005 Chivite, which I believe is Garnacha (Grenache). Cantalupo's Il Mimo (nebbiolo) is good too.
I have the 2005 Ch. d'Oupia Minervois rose, but haven't tried yet, but have liked previous vintages. Other wines that are usually good values include the Muga, Mas de Gourgonnier, Chinon roses from good makers.
Then there are the "serious" roses (in other words, over $20). Both Cotats make great Sancerre rose, and there's alway Tempier Bandol. The Lopez y Heredia Tondonia is great, but not a light refreshing summer quaffer.
