Tables with no belt change for 45's and 33's?

I have noticed that most high quality turntables are belt drive, and that you have to change the position of the belt (which is often under the platter) manually to alter the speed when you play 45's or 33's. Are there any quality tables out there that have a simple way to change the speed without moving a belt manually (which on my MMF-5 requires that you remove the glass platter)? Thanks,
