If I am being honest, in my opinion they are awful, I detest riding in them, unless I was using one because a horse was likely to change shape fairly soon, they would be last on my list for a dressage saddle. The only pros are that they are cheap and lightweight.
I had a small budget for a second hand dressage saddle, and managed to grab a Wintec 500 for £200. I'm really pleased with it. It fits my TB mare really well and looks very smart; I've had loads of people say 'wow, is that really a Wintec?!'
I decided personally to add bigger velcro blocks under the saddle flaps and would recommend that if you like a big knee block as the ones they come with aren't the biggest. I like the deeper seat as it is good for supporting my back.
Mine is black, but I've seen a few brown ones in the flesh and they are also very smart. I much prefer them in appearance over Thorowgood dressage saddles.
But of course it all depends on what fits your horse best
