Easy there with the wide angle eyepieces Simon & Neo!
There is an overwhelming range of choices and prices. You don't need those yet, Neo. Better spend some time getting an idea of what sort of things you like looking at and what magnifications are the most useful for you. The only accessories that I'd recommend at this stage is a barlow and a Cheshire/sighttube for collimation. A 2x barlow with the Bintel starter EPs (the 15 & 9mm in particular) will be useful for cranking up the magnification when seeing is good.
