If you'll only be doing eq, pleasure, and jumping...shouldn't you be looking at close contact/jumping saddles? Not all purpose?
And as for all those ebay saddles you listed...crap! Honestly, you'll be MUCH better off in a quality-made used saddle than a low-grade new package deal. Plus a used saddle will already be broken in. :)
Look for something Made in England. Or France. Or Germany. Basically all of Europe is good. And actually, newer Argentina-made saddles are coming up in the world (Pessoa & HDR for example). Many are made with European leather, but just assembled in Argentina to make the price lower.
Padded flaps are very trendy right now, so you can pick up a quality plain-flapped saddle for super cheap! Like a Crosby Prix des Nations.
In one of your other posts, you mentioned wanting to get everything together, not having to buy your fittings separate. Why is this? Wouldn't you like to pick out the appropriate size and quality of items used by you and your horse? Even still, many used quality saddles on eBay include fittings too.
