I'd not recommend either the Ingy or the SD.... While I LOVE the Ingy as an everyday watch, the rep with AR, lume, and Lello wheel is just too good for ~$500 USD. The big Ingy reps will probably be out this year, too. The SD, on the otherhand is one of those watches whose novelty will soon wear off, IMO.
I might consider a 97%+ used Ingy chrono. The secs at 6 rep isn't very desirable. And, of course, there are many a PAM I'd consider in your price range.
