I bought a belstaff cougar used for $600. I love the look and fit of it. It is a light leather but i like having that option in me closet. But i would never pay retail for one. If the price is right, buy it.
I have a few of their leather jackets from before they were acquired by Labelux in 2011. They aren't the same style as many of the jackets discussed here but it's nice to have the option. I looked at the first few seasons of the Labelux designs and they shifted too far too the fashion end of the spectrum for me.
I didn't (and wouldn't) pay retail. The quality was (is?) better than the average fashion brand, but is not as solid most of the brands that are popular here.
