Yay! Welcome to the club!
Believe it or not, I actually make my own. I use "blanks" then cut, trim, file and paint. I use little double sided sticky to keep them in place.
First photo shows my sticky tabs and the second is showing off my latest set using OPI Princesses Rule.
And having long nails... gah! I don't know how people do it. @Wallflower has her (homegrown, natural) nails long and when I showed her these I was complaining to her not understanding how she does anything with them this long.
