check out ebay. Go to flyfishing, search tioga, and you will find two 12's. One is offered by MikeScottsFlyshop(web) in SoCal. I have gotten 2 tiogas plus some spools from him and he has been super to deal with. Good luck.
However, save yourself the trouble and get the Standard Arbor if you are planning on loading up a Spey outfit. The 12 LA WILL NOT hold ANY backing with the Long Belly Lines (if you use long bellies). I learned that one the hard way and had to spend more money.
I have 6 Tiogas and have gotten them all off of Ebay. You'll save 50 to 60 bucks on a 12 buying off of ebay. Great Reels!
