Belle Glos Clark & Telephone Vineyards is one of my hands down favourites when it comes to American Pinot Noir, though it is a bit on the expensive side when you can find it... Belle Glos has two others closer to your price range, the Meomi is around $20 and is great value, and their Las Alturas is wonderful at $30-35. If you want to go French, try the Côtes D'Auxerre 2009/10, Cuvée du Manoir, Domaine Goisot pinot noir - it is phenomenal and very affordable at $20.
If you want to get really fancy, try to find a Champagne Blanc de Noirs, which is white champagne made from pinot noir. It can be hard to find, but I think personally it is excellent!
