We use a Brother 9020CDW colour laser/copier/scanner which is excellent. Has a sheet feeder for scanning, it will print 2-sided but not copy 2-sided. Quality is good and you can get good non-Brother toner cartridges.
This seems to the current version of the same thing with options in the range to go for additional connectivity and 2-sided copying:
