Thank you both Zal and Brendan, I really appreciate you both taking the time to give me some advice.
I think I've narrowed down my options to either the 12" Bintel Dob (going to do a bit more research on the brand and reviews to make sure I won't regret it) or the Skywatcher 12" Dob (which is $400 more expensive but if the brand is better I don't mind spending a bit extra).
As I've still got a few months til I'll be able to afford my telescope I'd also like to ask what brands and size eye pieces you recommend? I know the Dob's usually come with a couple but I may want to get a couple extra that I know will be good. And... a barlow??
Gosh, I've got telescopes on the brain, I even dreamt about them last night!
