Gosh, this a lot of cinsernation over buying a $14 ( including shipping) custom made Ti lid for a $30 Ti mug..
Good thing the OP is not buying a car or a house…It might require hiring a CPA ..:()
Seriously, I have owned all three ready made products suggested (Four Dog, MBD and Toaks lids)..
THE ONLY one I would waste my time and money buying for the SP 600 is the Four Dog titanium lid. It will fit the pot and is made of material that is at least as tough as the Snow Peak pot itself.
The Mini bull lid is nicely made but lacks long term durability and with shipping it wull be within a buck or two of the Four Dog Ti lidmm
Chances are, the Toaks lid will NOT fit the SP pot nearly as well as the two custom US made lids. Heck, most Toaks lids dont fit Toaks own pots worth a a sh#t let alone another makers;) Factoring shipping in, the Toaks lids are no stunning bargain for an ill fitting lid
Get the Four fog lid and worry about something else:)
BTW, the reason why the Four Dog staff has not responded is that its FALL. A big part of their business is their line of LW tent wood burning stoves..Hunters and Outitters love them and its their busy season. Its a very snall familly owned business with a handful of employees.
Trust them with your hard earned $14 by making an online order and I bet your lid us in hand within two weeks. IMHO, it’s money well spent.
