The bridle looks fine to me and, with it being the price it is, I seriously doubt it's poor quality. Maybe not the absolute best, but certainly functional.
The thing about buying saddles, no matter where you go, is you run the risk of getting one that doesn't fit. At least with a good quality used, if it doesn't fit, it won't be because it was built on a bent/cracked tree or the flocking was stuffed and left lumpy or lopsided. A good saddle is usually a relatively easy re-sale.
Though if you could visit with a saddle fitter or even try some saddles that belong to friends or at the local tack shop (my local shop will let you bring your horse in and try saddles on them in the parking lot to find one that fits). That will at least let you know what tree size you need for when you're shopping online. OR, you might find a really nice used one that fits at the tack store and save yourself all kinds of headaches.
