Having tried a number of different aftermarket double din units, I would be very interested in trying out one of these units, even at that price. Provided it performs well and is decent quality, i don't think its too expensive as I would attach a premium for it to look oem.
Over the years I've tried a number of double din units from parrot, pioneer and most recently a 'floating' unit from Joying. None of them have work particularly well, the parrot unit was one of the first android head units so that one doesn't really count. The pioneer was the first of the carplay compatible headunits and even though it was decent quality, it still required jumping through a bunch of hoops to get it wired in to the oem loom so I didn't strip the car down entirely just to run new speaker wires (I also wired in a new power amp). The same issue goes for the joying unit, but has additional problems. I had not been massively keen on the 6" screen on the pioneer, so I went for a floating 8" screen with the joying, this fixes the screen real estate problem, but it also hides the rest of the buttons on the centre console, so not ideal for turning on the rear wiper!.
Aftermarket headunits might look cheap in comparison, but if you look at Alpines freestyle X703D-F version, which might provide a decent install, or one of pioneers newer floating style units (DMH-WC6600NEX), they aren't much cheaper than this PCCM one, and you have to put up with the terrible quality double din surrounds that are out there and budget for a new amp and awkward installation.
If I wasn't looking at selling my car, I'd be seriously considering one of these.
