What would be good for DIY nails?

People basically get their nails done a lot, too, right?

I used to get my nails done regularly at a salon, but lately, even the cost per visit has become a burden.

I want to get my nails done nicely, but going to a salon is a hassle... and these days, there are products that allow you to do DIY nails well and affordably.

There are a lot of products coming up; which one is the best among the ones you've used?
