I actually have a black petal and a frosty flake that I have yet to assemble. They're still just sitting there in the packaging.
I use one if these rosewills as a daily driver at work. It's modded to ghetto greens. I think they are great keyboards for what they cost. EDIT: This was actually my first mech board too. Great starter board I think.
I'm think about putting browns in this one. I want to try them, and also want my wife to try them. She is using a rosewill at work now that I made up for her with vintage ghetto reds. She likes those, so I want to see if she likes browns too.
Would it be cheaper to buy a cherry POS board with blacks and spring mod them to 45g red?
Yeah, it probably would be. It would be a lot more work though to open the switches. And the person I did this keyboard for wanted the red switches.
I have swapped many blue springs into black switches to make ghetto reds. I personally just don't type on reds though, too light for me.
