Swiss is dirty yes, but to say it's dirtier than Pyrodex is pure blasphemy Pete!!! OE is just a bit dirtier than Swiss but not by much that I could tell the few times I used it.

MD is probably correct as to why it's priced the way it is Pete. And if you look at shipping overseas and hazmat charges and such you will see why it's so much cheaper than Swiss. I've no clue why OE is only marginally more expensive than reg Goex other than they just have a good mark up on Goex and don't charge such a high mark up on OE. If they did, then they wouldn't sell much because if they were close in price comparison to the better known Swiss people wouldn't buy it.
