Most of the rods I build are fly rods using blanks manufactured by Batson. Batson manufactures blanks for many major rod companies, including SAGE, G. Loomis, Northfork and Winston. They make a quality, durable product at a great price and LIFETIME WARRANTY.
Price depends on exactly what you want - type/size of rod and components, but as a reference point a 9 foot 5 weight fast action rod (comparable to a Sage X) would run approximately $399 + shipping.
I can also build one from the blank of your choice if you'd like something different - Sage, Northfork, Scott, Blue Halo, Echo, Winston, etc. but the price will vary depending on how much the blank is.
Handles and fighting butts can be of varying grades. Guides can also vary depending on material - chrome, titanium carbide, etc. Reel seats can be various colors and materials including beautifully hand-crafted wood inserts made locally.
Whatever you choose, the goal is to catch fish and nobody has ever caught a fish while sitting at home. So quit wishing and GO FISHING!
