Picked this up today (Swindon) after spotting it on Lidl's website a few days ago; thought it was a good in-store price for a classic 'guillotine' lever type cutter and roller trimmer combined. Essential for me as a photography student! It has a few safety enhancements too if you're cautious of children using it.
