its always going to be high when you try to use some of the best stuff, and have a platform to sell.
Its why I pick and choose the best stuff and have barrels done as needed generally, and assemble myself.
Thats the only way I get what I want, without having someone else sell me their ideas at a higher rate.
All in all though, for going price of customs its not anywhere out of range if you can't or won't put the parts together yourself.
