It all depends... are you looking to fill a run with books that fall within a range or must every book be a super tight whatever grade?
My experience with Lone Star / MY Comic Shop has been good and I believe they have tightened their grading in the past year or so.
If you are not super picky about the grade being dead on, I would recommend them. When I ordered copper age 9.4s, I got books that ranged from 9.0 - 9.4 in my opinion. I was filling a run with "near mint range" looking books, so I was fine with the results.
They are also a CBCA member, so they abide by our code of ethics.
With Mile High, copper age can be hit or miss. You could get a 9.4 or a Mile High "near mint" could be a 7.0.
High Grade and Comicana are great, but they focus on high end high grade books. They really don't cater to the buyer who is looking to fill a 26 year run, unless you want every book in 9.4 or higher.
I agree with Steve. My recommendations are for tight NM comics. Lone Star and Mile High are great sources for buying large quantities of comics if you aren't picky about the grade.
