much safer to project a solar image onto paper
even a small survey transit will produce a clear sharp 8'' dia sun with spots on white paper
as will a small telescope
and no way it can blind you
direct views of the sun can blind you
an older used scope is a good way to start outside his points deal
even a old mirror can be re-silvered [they use aluminum today]

cheaper but big and bulky are

I have a small cassegrain and two large 8'' newtonians one the wife ground as a kid
the other bought for the equitoral clockdrive mount paid about 200 each but years ago
truth is with hubble and web their pictures are so much better why ever try anymore to do your own ?
