They are a budget line with black finished hardware instead of chrome, classic cuban style banding, the wood is mahogony finished in a less polished fashion.

Some of these drums sound great and look pretty nice too.

I'd scoop them up right away.  I'm playing a set of mariano's.  I love the mahogany sound.  I bougt my set for $600, for a quinto and high conga.  I wouldn't sell them for $1500.  You can't get mahogany drums anymore because of the ban on importing it from Brazil.  When I got mine they had a crack in both drums, though not a major one.  These mahogany drums are famous for cracking, but I really don't think it affects the sound much.
  In some of the pictures I've seen of Munequitos de Matanzas, they play big fiberglass LP's for all the supporting parts, and a mahogany Gon Bops for the leads.  I think it's because of the crisp cutting sound of the mahogany drums!
  OK, I've rambled on long enough now!  To sum it up, my vote is BUY THEM!
