Re:
I hope someone in here may help but if not, as it's pretty much entry level kit, it's often worth looking to buy a trashed bike that has some good condtion kit on it, I've done this a few times and ended up with decent kit for peanuts before.
If using ebay then when on the search for a "bike", do not select new or used but select "for parts or not working" often there are little goldmines on bikes others feel are not worth tuppence.
