I am a huge fan of Imusa grease pots and the Stanco Grease Pot. They are both really cheap and work very well

Trangia offers both 1.5l and 1.75 aluminum pots... just aluminum or hard anodized... $15-40 depending on features and retailer.

Otherwise Imusa 1.5l grease dispenser, $8.99 from Amazon right now... gotta cut that handle down and probably find another lid solution to keep the weight proper ultralight. https://www.amazon.com/IMUSA-A004-70011W-Aluminum-Grease-Dispenser/dp/B0018EA048
