Thetford is a shit hole, i live 2 miles from it in the middle of the forest, however there are some fantastic villages around me that are still close enough for trains etc, i can be at redbridge train station in 1hr worst case, you will get alot for your money in Thetford but as has been said it's full of Eastern Europeans.

Look at some surrounding villages though and you will be surpised, I.E Culford, Icklingham, even the outskirts of Bury St Edmunds
