qmdv,
Not belabor your actual point

but, yes, the 7AC Champs are a great little airplane, honest as the day is long, and 1000 feet of grass is plenty, assuming no serious mitigating factors, like three foot tall grass, 300 foot obstacles at both ends, etc...
The Champs can be had in that price range at reasonable cost. Look for a 90 hp airplane, the 90's are very strong engines for this little airframe.
There's a 7AC with 90 hp that I rent here some, and it's a fun little airplane. They are approved for spins, and have a fairly liberal loading envelope.
Note that these airplanes all had wooden spars, and there are AD's out there. No reason to be afraid of wood spars, but I'd look for one that's been recently rebuilt with new wood spars. A fellow here is in the process of rebuilding one if you're interested, though it'll be new when he's done, and the price may be a bit higher than you're considering. Let me know if you're interested, and I'll query him.
The spars are the main thing to look out for, but again, nothing to really fear, just don't be dumb in the purchase.
