Back when the Spinhx SDPs were $900 I picked one up. At that time no I didn't think they were worth it. Mine was very soft shooting but had numerous failures to eject unless I used 9mm that was bordering on +P. At the time KRISS also had zero parts, zero mags, really zero anything for the pistols when I called and asked and no idea when they might. I also found the trigger frankly subpar for the price. The SA was nice but the DA was, IMO, notably worse than a stock CZ. I sold the pistol. For the $750 I've seen them for lately I think they're in a more reasonable price bracket. I probably still wouldn't buy another.
