Nothing to add about the Tough 1 saddle. It is indeed trash. And yes, once you've handled a good saddle (Not even a super NICE saddle) you'll find the cheap ones to feel gross, fit horribly, and you'll want to set them on fire in the back yard.
Also keep in mind, if wisely bought, a good used saddle, even a mid-range quality, will hold its value, or even sell for MORE than you paid if you take care of it. Make a wise first purchase AFTER you've bought your horse and you can trade up or outright sell it and make money and reinvest it in a nicer saddle, rinse, repeat, until you're up in the really, really nice saddles.
MOST western saddles with FQHB will fit MOST quarter horses just fine.
But get your horse first - because you might find the perfect TWH or Arabian cross and a FQHB saddle won't fit them at all, or they might be a quarter horse that's built like a bulldozer... and you need a wide-tree saddle instead.
Be prepared to not go cheap on the pad either and for the same reason. A good pad is a life saver for you AND your horse, lasts years, and should have decent resale/trade off value if taken care of. You can start with a pro choice or classic equine and work your way up if you feel you need something even better.
I'd say for about $500.00 you could get a good USED set up from an individual and it would last you many long years and still have good trade value and be of good quality.
