Lowes has two Delta sliding miter saws for 45% off. Delta is a good brand and the two saws seem to get good reviews. The 10" model is 26-2240 and the 12" model is 26-2250. Sale ends 11/7/2018 but might end sooner.
Looks like this is a regional sale (thanks rellog321) so this might not be available in your area. I live in Virginia and it is on sale in my region.
