Visited Our local 'The Range' Store today and found that they have Revell Easy Kit model aircraft for £1.99 RRP £9.50). The lowest price I can find these elsewhere is £5.50 plus shipping on Amazon.
We have made one of the kits already and they are excellent. I think they are about 1/72 scale and are pre-painted and snap together.
Our store only had Tornado IDS and Eurofighter Typhoon.
