I have Vienna by Thornhill and like it a lot (also was the best fit out of bunch of saddles I tried). I use it for 3 years or so, and it still looks like new after I clean/condition (which I do usually once a month or 2). Several other people on forum own Vienna and also very happy with it (it puts the rider in a correct position and very comfy to sit on).
I did try Klasse as well, and it was a very nice saddle (although more expensive than Vienna). Unfortunately it wasn't such a good fit, so I passed on Klasse. Keep in mind though that Thornhill is a good fit for wide horses, and Klasse seemed to be even wider than my Vienna (therefore bad fit even with medium size tree).
P.S. Stay away from all those cheap "packages". You get what you pay for - junk that doesn't usually fit the horse and uncomfortable to ride.
