Yeah, I did the same thing, went into Sport Mart and bought a $300 doller bike. Lets see how much I have put into it now.
1. New Fork $80.00 + $20.00 For Labour.
2. New Hub $20.00 + $20.00 for Labour
3. Atlest 3 new Inner Tubes. $10.00 For All.
4. 1 Brake Tune Up $30.00
Total = $180.00
+ $300.00
--------
$480.00
So it has turned into a $480.00 doller bike. Not too Much more but that's $480.00 I could have saved up to buy a better bike. Now that I am more into mountain biking, I need something better to take the abuse. But when I has 10, a $300.00 bike you buy yourself seems really good. But now that I do harder stuff, it just seems like a hunk of scrap metal
