Thank you I didi find this review before.There don't seem to be any thorough reviews, this https://hifireference.com/reviews/denon-dp-450usb-review/ seems typical. BTW, the 450 differs only in the adition of an ADC for ripping vinyl.
Not necessarily. Although preferably most simple elliptical styli that come fitted to cheap turntables will play a 78 speed LP. The fact that most of them are mono may then need a different cartridge.78s are a completely different kettle of fish. You will need a different cartridge to play them. Switching cartridges is not easy on most record players, even if they have a 78 setting.
