Hello Gareth,
Here is a website that I found a while back that I thought was quite useful for comparing eyepieces. A pity they dont have more newtonian sizes, but what do you expect in a free program! The eypiece selections are very good.

Also, as a bit of a laugh, here is a picture of my old Amasco 50mm refractor I got when I was 13 next to my present telescope, a slight improvement. Even with this small scope I was able to see saturns rings, M42, jupiter and moons and lots of other things which I had no idea of what they were but they looked good. Here I am now 32 years later and more hooked than ever.
