If you have any Asian/Korean markets near you, look for a chip called 꼬깔콘 (Kokkal Cone) Popping Corn chips.
They are the Korean equivalent of bugles, albeit imo a bit sweeter and less savory. Still beats not having bugles at all!
EDIT: There is a version of said chip that comes with closed triangles instead of cones… you will have to find the version with cones. It looks like this, except the original flavor has a red bag.
It ain't much, but it's honest work (slrpnk.net)
Bugle chips, are just the recycled taps that they use for the stalks.
