I would recommend B & B Appliance in Escondido. We were shopping for a double oven and a cooktop. I found B & B to be extremely knowledgable, much more specialized and informative than a best buy/fry’s experience where the same person selling appliances also sells ipods. B & B also does warranty repairs, so they had a lot of insight about specific models to steer away from due to known issues. They ended up matching the best price we found, which I believe was sale price on Best Buy’s website.
We ended up with Bosch for cooktop and double oven and have been very pleased so far.
Our friends bought all Dacor (also from B&B) and have been happy with that brand as well.
