MBP, (as you know I'm positive) it'll depend on horse a lot what we can suggest.
I have Thornhill Vienna that was the best fit out of bunch I tried (including pricey used Black Country). It's under $1000, but nice quality, put in good position (in fact one of the very few saddles that do for me), and it's wool flocked (I had it re-flocked just couple months back because my horses changed so much in work). Their Klasse is even nicer (but wider too for the same tree size). I also really liked MT (although my fitter didn't quite like the billets there). BUT my horses are on wider side (even TB-background paint).
If your TB is on more narrow side I'd rather look into Stubben and Passier (neither was a good option for my mares). I've seen "looking like new" Stubben in my local consignment store for just $1000 (I borrowed just because it looked so good for the price, but it was (expectantly) bad fit).
