It's usually best to try out products before you buy a whole system. Nearly all brands have an intro kit that isn't too expensive with small samples of everything you need that they sell so you can do a few sets to try them out. Go online and read reviews, view videos, etc. of other brands. You need to do your research since you're going to be the one buying your product. CND has different formulations that do different things. Go to their website and they explain what Radical, Moxie, etc. are designed for. Frankly, CND can be on the more expensive side, but their products are high quality, reliable, and they cater to professionals.
Usually any acrylic called "competition" is going to be a fast-drying product. I use Hand and Nail Harmony brand acrylic and gels but I am certified in other brands. I like Harmony's products but they have issues with some of their Gelish gel polish colors fading, and their clear acrylic powder isn't as clear as I would like. I like what I've seen of Crystal Nails on the internet, I would give them a try myself, and Young Nails seems very popular.
To be honest, you just have to try things out. It's like buying clothes, you have to try them on or you just never know if they are the right "fit" for you :wink2:
