09 Glory is getting a bit dated and probably not worth it. Frame design was updated for 2010 with geo tweaked for 2013. If you have your heart set on a Glory, I'd go 2010 or later. $1-1500 should get you a decent enough.
EDIT: That being said, I think you should probably stick to the hardtail a bit longer. If it's well set up (good brakes, chain guide and 2.5-7 tyres), you can ride pretty hard and ultimately it'll teach you to be a smoother rider instead of just going straight to a FS bike and plowing everything. Just my 2c.
Personally I hated the updated geo, Id pick the older model over the updated one anyday (except a 2013 where its been dramatically fixed).
For me I liked the older one, they are heavish, but its mostly low down and the frames are so solid you don't really need to worry about breaking it too much, they pedal and take the rough like a boss.If its good condition and its the right price (it is getting old so Id make sure you're not spending too much) but if its good price range, give it a good check make sure the frame is in good condition, check all the welds and the frame for any signs of damage.
If its a full build check the parts too.
but I think the older glory is a great bike. I have a mate who still races one and does pretty well in his category I believe.
The newer 2010 (not sure on 2011 onwards) had cracking issue of the frame.
Keep in mind the weight will depend on the build and sizing. Stock from what I have seen ranged from 19-20kg but people have gotten them down into the 17's. Find one that's a good build and find out the weight you might be surprised.
