My nephew beleves the #2 bike to be a PK Ripper. If so it is probably the best bike in the group.
Prices are harder to give, I always say it is worth every dime of whatever someone will give, but certainly less than what the investors expect to make off them.
The recent $2700 Krate Disc Brake rear wheels on eBay are a prime example. Some buttmunch can think he will get that all day long, but at the end of the day (week, month, year or lifetime you pick) he is still the proud if not ignorant or greedy owner of one.
To be honest, it looks like one I built from parts about 10 years ago for about $300 including the tire.
You can look them up by the names I gave and see what they sell for, or if you need me to I could do it for you but I would need a couple days to get caught up on the ones I am researching already.
