I should have mentioned; I can't buy off the internet/phone anything like that. My dad doesn't like that sorta thing.
I have a 8" saxon dob. People on Skype have reccomended that I look into getting a Meade #140 Barlow and a 9mm eyepiece. Then just a solar and light-reducing filter.
Sound good?

p.s -
www.sirius-optics.com.au is where I will be buying from [website of the store where i'll be going]
EDIT- That has some nice ones in my pricerange; probably the Orion ones.
