Why Not Semi-Automatic Style Turntables?

I think it is probably because that most people think that if the record is over, you have to get up and change the record, or turn the system off, anyway. This thinking is okay, as long as you don't fall asleep during listening. if you tend to fall asleep, then there are at least 2 models that I know of called "The Lift" that can be put on just about any manual turntable. They have a high, and low price model, both under $100. Simple, stick-on installation. It seems to be a copy of the old Monitor Audio arm lifter from the 1970s. I believe it is available through Expressimo Audio website.

Probably for a similar reason that high-end cd changers are rare and many preamps are made w/out remotes. I wouldn't pay extra for a lift. I don't have a remote.

I think it's unreasonable not to expect that many users would want the convenience of a lift or remote if it doesn't harm the sound quality. Does the cost of such an ammendment increase proportionally to the list cost of the unit???
