Brand New Hero's Engines

We have a number of brand new Hero's Engines surplus to requirement. Each is £42 from Philip Harris. We would like to exchange them for some equipment and are open to any offers of equipment suitable for levels up to GCSE. It doesn't have to up to the same value retail. If this is something you might be interested in please drop me a message and we can work out something that's mutually beneficial to both our schools.
