A good sign of a good English Ceilidh Band is a good range of danceable schottisches. Others of course will have different opinions... So, in alphabetical order, and without really knowing whether they are officially schottisches but on the principle that the feet tend to do the right thing.
For a collection of tunes as small Gif's see Richard Robinson's tunebook. The tunes sorted by type contains a few schottishes.
More suggestions or links anyone? Even a definitive spelling of schottische, schottisch, schottishe, schottish, scottische scottisch or scottishe would help!
