hehe sorry! I guess I should have just asked 1st
Like I said i'm a new comer too so don't really know anything about the bushmaster.
Andrewscom have similar specced telescopes for $300-$400 from skywatcher, celestron and guan sheng.

so if the bushmaster is in a similar league it may be a good deal. From my limited experience, the question I would be asking is if this scope uses 1.25" eyepieces. I borrowed a refractor that had the 0.9" eyepieces and it was rubbish, I personally would not recommend anything that doesn't use at least the 1.25" and I thing it would easily be worth the $100 extra to get a scope that does.
Actually, for the extra $100 I bet a lot of people would tell you to go for a Guan Sheng GS-580 Limited 150 x 1200 $299.00 AUD, and for another $100 you could get Guan Sheng GS-680 200 x 1200 Limited version $399.00 AUD about 3 times the light gathering power for twice the price.
a LOT more bang for your buck
