| Hahahah, i see it happen all the time at the bike shop i work in, guy comes in and buys a $40 pump and then comes back two weeks later because it doesn't work as well as he wants so he buys the the $80 one i suggested in the first place. So instead of something costing him $80 he pays $120 for it! Hahahah...
The X4 is cool but you could be fine with the X3 providing your not a big tall heavy guy. My first bike was small and had 10" wheels and i wanted my new bike to be bigger and more stable and i looked at the idea of the X4 too. But after sitting on an X3 that had a 10/12 wheel combo i knew it would be sweet. I run my X3 with 12" wheels and i could not ever see myself putting a 14" up front. The bikes wheelbase is sweet and it sits at a perfect height, not too big but not small and sketchy either.
Either bike will be sick but depending on how tall you are and what you want to do, that will be your deciding factor...
