Fruit Bushes

I have just finished my fruit beds and have room for one more bush, I would like to try something a little different.  I already have gooseberries, blackberries, tayberries, black currents, red currents and white currents.  The space is in a middle bed with no supports so it will need to be a bush of some sort.  Any one any suggestions.

Try a josta berry 

Other plots have them, and I tried and liked them, so I planted mine last year - I hope it will fruit this year
