Dumb Question Thread - No Flaming Allowed

[PSUEng]

Doing some searching on fuel pump lock ring tools and just like seemingly everything else there are a ton of choices. Genuine BMW tool (#161020) is out due to price, but the BAUM, AST and Schwaben offerings look very similar to the genuine tool. Then there are CTA & BavAuto tools that look similar to one another but different from the genuine tool (complete circular contact with ring vs. open sides).

For those of you using one of these tools, which brand(s) are recommended?

Cheapest one as you'll probably only use it once. Or stick with the ol' multitasker - large flat head and a hammer lol
