Hey Fulgour,
For a family Christmas present, I bought a refractor scope that is 150 (diameter) and 1000 (focus) with additional eye pieces (including filters).
Sometimes I use the moon filter (when it's a full moon and it's very bright).
I did a fair bit of research before buying and I found some websites that showed pictures of what you could expect to see with various different scopes.
Let me know if you want me to track down those websites for you.
If you need to stick to a budget, my advice would be to go for a better scope now, and accessories later.
Better still, try and find some astronomical societies near you. Usually there are lots of people that are willing to share their knowledge and advice and you can look through their scopes and see which ones you like for yourself.
Cheers
