Liberty Flights has them. They are like $43. Use the code ECF for 20% off
IDK about the sigelei's. I do have 1 and it does not fit. IDK which it is. It has the matte tele body with the polished top and bottom caps. Its a GGTS clone. Hope that helps.
Thanks Kwalka, that is very helpful. Disappointing that it won't work for me. I am pretty sure the threading is the same on the 8, 13, and the 19 so if it doesn't work for one...
And wow, $43 bucks for an outdated AGA! I guess they read this thread too! Lol!
