[Buying] Flame Spray -- honest traders only

Looking for a Flame Spray (Uncommon gadget). I've got gear and mats to barter -- tell me what you actually want instead of 'best offer'. Honest traders only, I've read enough horror stories this week.

Would a stack of mats plus something spare be fair for this? Still learning what things are worth.

Vouch for this trader, done clean deals before. Barter's fair, no games.
