Forget solar shingles?

Panels: Still the best way to go solar?

So, I need to re-roof my home and I thought that that this might be the perfect opportunity to convert a percentage of my roof to solar shingles. Thus, I've talked to a number of solar integrators and every single one of them, thus far, has told me to go with traditional solar panels rather than solar shingles.

According to my contacts, solar shingles are still too expensive and too unproven. More important, each told me it would still be cheaper to re-roof my house, then add a solar system, versus re-roofing with solar shingles.

Anybody out there recently gone to solar shingles? Any thoughts?
