Breakers for a low flow machine

[SlowDave]

I am planning on purchasing a breaker for my Bobcat 443B. As I understand it the auxiliary flow is only 6.8. Blue Diamond is the only one I have found that works with this low flow. But the Blue Diamond price is a bit over the top and they don't even throw in complementary Vaseline. I prefer buying used because I am a tight wad. So what brands and models will work on such low flow.

Thanks in advance.
