Deep Freeze

I want to buy a deep freeze but not a large one. I have the usual freezer/fridge combo in my kitchen but would like to have somewhere for overflow purchases. Any recommendations or what should I look out for?

Ideally get an A rated appliance to save on total cost of ownership/running costs.

Just had the same problem as you. Got beko upright freezer (7 cubic feet)
Looks like big fridge about 6 foot high with silver door. Got a frost free one for €340 in currys. I had shopped around and this was a great price for frost free. Didn't mind colour as it is only going out into the shed.
let me know how you get on
