Looking for Appaloosa Stallion

Either to buy or breed to once. Must be foundation or second generation, 500+ stats, within the ages of 16-20 preferably. Colour does not matter, must be SJ or (if foundation able to convert and I'll offer 2 EVC to convert back). Looking for low non-specs unless converting a foundation. Preferably the less foals (under 5) the better. PM or post a link to your stallion. Price is not an issue.

I've got this guy, So Overo-It, that fits. I'd be willing to stud hm

And then I've got one other possible stud, but he's lower in stats than you want and has 5 foals already (will probably have 3 more max). He's here.
