I was hoping for a simple, screw in type extender... I don't want to disassemble the joystick, and also, the price, 15 dollars for a piece of metal seems a little stiff. Anyway, I keep it in mind as a last resort.
$15 + shipping from Hawaii!
Same price priority shipping as any store in the US, and.... we send chocolate.
We just ran a sale on shafts too!
LS-32 shafts are not the same size as Sanwa shafts, so be careful on using the adpaters.
The shafts are stainless and hollow, the hollow bore increases the cost significantly on machining. We also have the Twist.

(short, regular, twist regular, long)
The Twist offers three different length options for only $15, including a short shaft. These are 15 plus $6 priority shipping to any where in the US. You can get 2 for 30, plus $6 priority shipping anywhere in the US, or get about 20, for 300, plus $6 priority shipping anywhere in the US...

Sorry the shipping costs being expensive is a common misperception. Everything we ship goes flat rate. Unlike many vendors who go by weight (which for priority mail will cost more than using flat rate boxes) we have everything set up to automatically assign to a flat rate box. Susan is an AMAZING packer and will use the least expensive shipping she can using priority. If you email her and request it, items can be sent first class. I have priced our shipping against most vendors in the US and we are the same or cheaper than all I compared with for comparable products.
