I recently bought the all-in-one Epson Stylus SX215 for around £50, discounted from £100. I also bought a set of 12 colour ink cartridges for £12, which is (Imo!) good value.
I won't pretend that I know a lot about printers, d: but it does what I need it to. It prints relatively fast, and when printing photographs or high resolution documents it prints accurately and produces great monitor-true colours.
To be honest I only really needed it to print out text-heavy documents for university so I haven't mucked around with the scanner yet. I assume it's good though! It came with a CD including a lot of programmes for easy photo and print editing, accepts USB sticks/cards, and has a little interactive screen which is handy.
My old printer was ancient and the cartridges cost a whopping £30, so this is a real upgrade for me. I haven't had any problems with it and the installation was easy.
I bought it from Amazon and the reviews were good! I paid for standard delivery and it turned up the next day which was brilliant.

One thing I will say is that it doesn't come with a printer-to-computer USB, so make sure you've got one to hand or invest.
