Sheble's
My ATP with Sheble was just over thirteen years ago, so things may have changed since then. It was in Blythe, California. Of course, he's moved to Nevada since then. I believe he now uses a Travelair.
They were using a Duchess then. I had a friend who had gotten his Commercial Multi at Sheble's four months before (all 3.0 hours worth) and he gave me all the study guides, V speeds and whatnot. I had memorized all that information. I had also practiced the BLH approaches many times in the sim, so I felt I was ready for them, though I had no idea what NDB approach they'd use.
I got there and found out the NDB approach would be given in their "sim." I say "sim" because it didn't fly like an airplane or any other flight training device I had flown before. It flew like an Etch-A-Sketch. I recall the approach had a racetrack procedure turn. I was tracking inbound to the IAF and a parallel entry was appropriate, per the AIM. I did it and my instructor was satisfied.
The next morning we flew the airplane. I didn't have a lot of multi at the time and had no time in Duchesses, but I apparently did well enough to satisfy my instructor. Then came the practical.
The oral must have lasted five minutes. Ten minutes max. I don't recall what questions I was asked. I read the comments above about the four-hour orals and I agree. But, a ten minute oral is just as ridiculous. I didn't complain, though.
I believe the flight came next. I don't recall the details too well, except that I did steep turns, maybe one stall, maybe an all-engine VOR to a circle-to-land and a single-engine ILS. All under the hood, of course. I remember the examiner was yakking the entire time. I remember being not especially rested and somewhat nervous.
We came in and I did the NDB and the hold. I didn't track as straight during my parallel entry to the hold as I did the night before, but it was fine. The examiner told my instructor to have me try a teardrop entry (non-standard, per the AIM!

) to the hold, which I did while he watched. All the while, he was selling me on the merits of his teardrop entry. Then, I was through. He rubber-stamped my logbook and signed it. In the meantime, a lady at the desk had typed my temporary, which he signed, and I was out of there. In at 4:00 p.m. Sunday afternoon, out by 12:00 noon on Monday.
I would go to Sheble's again, but if you go, go well-prepared. I left happy and with my ATP, but, in thinking back now, I wished I would have been better prepared for the pace. I don't feel I received much training, but the place made no pretentions about giving you flight training. It just gives you an intro to the airplane and reviews the ride gouge with you.
Hope that helps.
