CND Shellac takes 10mins max to soak off. If it's taking an hour, it's probably not CND Shellac in the bottle. Even a gel polish shouldn't take an hour's worth of soaking.
Brand wise there's loads. Gelish, Gel 2, Gellux, Cuccio, IBD, Orly GelFX, Jessica Geleration to name but a few.
I'd use the search facility on here and have a trawl through the threads to see which you like the sound of, then check out colour ranges and ensure you're using the official supplier. Cost wise, some vary by a few pounds per bottle but don't be just price led. When you work out the cost per service, they can actually be really similar.
I use CND Shellac and am considering Gel 2 (recently launched in UK) to providr the colours that aren't available with CND
