Anyone use Salonsystem?

[noodles]

Does anyone use Salonsystems for either gel nails, or mani/pedi? I'm trying to decide on a new product range to use for manis and wanted to know what people thought of the Salonsystems products. And are their gels any good? Also, my gels/mani/pedi qualifications are through NSI and Sparitual. Can I still use Salonsystem products or would I need to do one of their courses first?
Thanks
