Hi Luis,
I own the Roland V-Stand, and as far as it not being level, I had to check for myself. Upon looking at it, it looked pretty level to me, so, having a lot of time on my hands, I got my level out to check. With the weight of my G70, it tilts downward EVER SO SLIGHTLY, but I hadn't even noticed it before nor has it affected my playing. The horizontal supports fold over into small cradles and I imagine if you wanted to bring it up a bit, you could put a small folded piece of paper or something into these cradles to get the level how you like it. But for all intents and purposes, it is level. I'd go for it, it is very sturdy for the weight of the G70 and it looks great too.
