I can relate to Timpo.  

I didn't want to spend the money on a kit.  But, I don't think Ryca is really overpriced either.  I've purchased several parts from them that I could have found a little cheaper.  But, I know their parts will do exactly what I need so I don't mind the little extra I spent on those.  There were other parts I copied and a few that I made based on the parts I was using.  

In the end, I spent around $2,500 $1,700 on my build plus the cost of my bike. I didn't spend a much of money on any of the parts you listed (my tank was $60 shipped) and I didn't do any paint or chrome.  I did have to spend a lot of time chasing/fabricating parts and had to borrow a friends welder.  So if you look at what you get from Ryca it's not really out of line at all.  

EDIT:  Wrong price.
