Bore guides

What bore guides are you guys using, I see that there are some many to choose from? Anyone using a Lucas guide, if so how do you rate it?
thanks,

FIELD FABRICATE TO SUIT: Cut the top of a fired cartridge case (from weapon of choice) below the shoulder. Viola! Little brass funnel, or thimble. Peen big end flat for grasping. priceless...
