Recommendations for tinting products!

[BrowQuarter]

I am opening a brow bar in a few weeks in a large retailer and am looking for recommendations for a tinting brand.
I have heard good reviews from both Appraise and RefectoCil and would like some views and opinions on these or any other brand someone uses. I want the same effects as HD tint but without the price tag.
Thanks
