Salon express is a lot like the brand called Konad, from Korea I think that have the original version of this DIY style of nail stamping, I thought I'd give the cheaper one a go and see how I like it before I commit to the original.
The kit comes with five plates with a myriad of more then 40 designs, I read that you can get different designs in different kits but these are the ones I received, not the cutest unfortunately but you can buy additional plates online:

After just a few goes I was pretty happy with my results. My best piece of advice for you is to make sure you REALLY get the angle right when you are scraping off the extra nail polish. I found tilting the scraper at about 45 degrees made all the difference.
One negative I did find is that the whole nail designs that came with the kit were too small to cover my entire nails. it covered my pinky fine but there is a hope in hell it would fit my thumb!
Like all things in life it takes a bit of practise and the right tools to get it right. You can use normal nail polish with the kit, but I highly recommend to use the highly pigmented colours sold by Konad and other brands. I found that the white polish sold for use in French Manicures comes up nicely though.
If you're interested in buying more plates for your kit, I have found a store online that stocks Konad and other plates and special polishes. I have to say now that I haven't bought from them yet but I'm in the process of putting an order through now, I'll let you know how it goes! They also have an eBay store that sells stock for a little more but gives you the peace of mind that comes from eBay shopping.
Have you tried at home nail stamping? How did you go?
