We switched from inkjet to a cheap HP laser from John Lewis - an HP MFP19fmw - and have been astounded by the improvement. The first colour cartridge is warning of possible replacement after 5 months but they say it still has 10-15% left and you only replace when you see actual degradation. Cost of new toner is £ 49 - not so different to buying Epson inkjet cartridges.
Only issue is the HP doesn't scan two sided - have to spend more for that.
I had some issues setting it up (all one off local things) and HP support were really good
