I don't think using a walker has anything to do with walking early.
DS took his first steps at 9 months and a was a full time walker by 11 months and I never had a walker. I also walked at 10 months and my parents never used a walker either.
Also, as far as anything goes: walker, jumperoo, exersaucer...your baby should never "always be in them."
But to answer your question, yes. They still make them.
