I looked at the pinnacle and thought it was very good for the money. I think you go with whichever feels better for you and whichever has the highest spec for your money. I was also in the "do I spend an extra £50?" Frame of mind. You have to be careful on one hand cause you end up over spending but then while you're investing had you mays well get what you want...?
I went into
halfords today as they are giving away free services for O2 and they have some dreadful bikes in there. I know they have some quality ones but the toy crap ones put me off them as a serious dealer if that makes sense??
Hope you get one soon. I know how hard it is to decide on a budget.
