So after seeing my Asian Classic Dish thread get a lot of attention, I noticed that people recommended using the "fake Spam" instead of the real thing. So I decided to go to Safeway and buy every single type of Spam/Luncheon Meat and try them all out to see which one was the best for the noodles/spam/egg dish.
Here's what Safeway had available for me:
The 5 brands are, Holiday, Safeway, Authentic Spam, Klik, and Prem. First thing I noticed is with the exception of Spam, the other 4 brands use the same "key" system to unlock the tasty mystery meat.
Looking at who makes them shows that 3 of those, Klik, Prem and Holiday, are made by Maple Leaf.
The Safeway brand was "Prepared for Safeway"... if I had to guess I'd say it's made by Maple Leaf as well.
Spam of course was made by Hormel, the original inventors of such a great product.
