EDIT, I noticed you already purchased a gun, but I will leave this for future people who are interested.

Hey, when you say sporting clay, I am going to assume skeet because you are looking for OUs. I was in the same situation before the summer skeet season started and had exact budget limits that you have. The only difference is that I wanted a gun that would be 90% clays 10% field.
I started looking at all of the entry level guns like Condors, 555s, silver reserve and a few others. Of these the stoeger condor competition was in the lead based on internet research. However, when I actually found these guns and played around with them, I couldn't in good conscience buy one. The fit/finish and most importantly, perceived value, was much lower than I would have imagined. I wanted something that I thought, as a rational and very technical person, could hold up to a lot of hobby shooting, not hundreds of flats a year, but certainly 1000+ rounds a year. As it turns out, I am going to hit that number pretty easily only having owned the gun since fathers day.
This took me to guns made in Italy and a few that were European. I looked at the Bettinsoli, CZ, Franchi and a couple other OUs that don't come to me right now. Also because of what I had seen people using on the skeet range, this 'next level' let me look at a couple of semis as well.
I checked out all of the used boards, guntrader, firearms Canada, etc,etc. Went to look at a few decent priced OUs from the Bs and a few ruger red labels. Side note, I would say that 20% of the ads I replied to were scams.
Long story short, I ended up with a Franchi Instinct L. It had all of the features I wanted (single select trigger, mechanical triggers, 3" chamber, 28" barrels, 7 year warranty and it was a decent weight). The CZ has double triggers, which are not for me, the Bettinsoli was too slender. I actually would have bought a used Beretta Urika 2 if I could have found one in mint condition at the time - and I am glad I didn't. The visible safety factor of the OU, being broken when not shooting certainly makes everyone a lot calmer, and you know, it looks cool too. However, breaking a OU in a duck blind or canoe is going to suck...
Everyone was 'save more, spend more', buy a B gun. 'Buy once, cry once', etc. Hard to argue, but unless you really know your stuff, you could end up with a really old one that has been modified or worse. I saw a lot of guns that were fixed choke at one time but had been bored for removable, and the amount of remaining metal was scary to say the least. Actually there is an used beretta in a store right now (BIG chain store) that is just like that, I certainly wouldn't trust it. A lot of guns become 30+ year safe queens and its tough to figure out the history. Your gut feeling can save you a lot of grief.
Buyer beware, so I bought new, stayed in my budget and happy to say that nearly 40 rounds of skeet later, and many pasture clay sessions, it is just getting better.
Don't cave to pressure and buy a gun you don't like because it is supposed to be better. Go to a knowledgeable store, and find someone who can tell you if it fits properly or what would need to be done to make it fit properly. I will say that I am 6'3 with long arms and big, but slender hands and the Franchi fit me better than almost all of the more expensive guns that people let me try on the field.
You had mentioned the Instinct SL, I personally would say that it is far too light for any amount of clays.
