Hi, I'm fairly new to biking and am having a hard time figuring out how these part group sets are going together to make a "better" build then some others and would really appreciate some help and advice. I'm not in the market for a large budget bike, aiming for under 1,000CND out the door. The bike is going to be used to learn how to attack much tougher trails and inclines that my current bike just breaks on. I've found a few bikes that seems like they would fit the bill for what I need which is :

• Need something more reliable then a boxstore supercycle (mine just breaks)
• Would like to keep the bike and just pay for small upgrades as I go.
• I am a girl and really do want to have a soft colour on my bike (i.e light blue pastels)

I'm just hoping someone can give me a little direction as to what I need to be looking for or avoid. The bikes I've found I'd like some feedback on, please feel free to pick them apart, information is handy when approaching bike shops.
