Any info on Tong-ah?

I got mine from Korean Gungsulwon for 160 dollars but it doesn't look like they're offering them on ebay anymore.  I learned to shoot it myself by watching youtube videos.  You can find a ton of them there if you haven't already.

I'd be curious to see what the quality is like on the one that Koreanbows.com offers.

I made my own to what I could gather was 'historical measurements' or 'standard measurements' (28 inches and a certain diameter that I can't recall off the top of my head).  Everything was fine except it was too short for me.  So I purchased from Gungsulwon and theirs was 31 inches came with 3 baby arrows and was far more comfortable for my draw.  Plus it was lacquered and had a few other features mine didn't.  Its totally doable to make one w/o lacquered and very basic yet functional like mine.  The hardest part was picking out the proper piece of bamboo.  Basically, nature has to provide a shoot with the correct measurements.  It was far more easier too to get the right shoot at 28 inches than at 31.
