If the brush whips up a good lather and it feels okay on your skin, then it's a good enough brush in my book - a more expensive brush will feel better / last longer / look better, but it won't shave better.With that in mind, here is my current brush collection minus my travel brush* and shaving-at-work brush** (click the pictures to make them bigger). None of these are budget breakers, and all of them makes great lather and feels great-to-good on my face.
As they sit on my shaving shelf - the tray is just to help organise them.
