I'm a $15 to $20 / bottle guy.
I like Rhones, Pinot Noir (especially from France and NZ) and non-oaked whites. I've found I can drink quite well at that price point.
Pretty much all of my shopping is done at a wine shop up the road from me...K&L wines:
www.klwines.com They have a 'premium' wine club - 2 bottles per month at $15-$20 each, from pretty much all over, so it's a good way to try new things.
