@TomTomBinks,
American Standard is good and it's cheap. You can buy the small flush or the big flush type.
Problem today: A quality toliet seat ( one that you buy at a hardware store and lock into place yourself can be expensive. The old wooden seats, lasted a long time but were somewhat uncomfortable.
When i was a college student. I went to a junk yard and bought a used ,red , wooden toilet seat that had been discarded by a Chicago nightcub...I had a green bathroom, so any time I went into the bathroom, I thought it was a merry old place to be in..Green walls + red toilet seat.
