Is this end mill really worth 90 dollars?

Is there an alternative?

So far its the only one like it I have found. Carbide, 1/4 radius, 1/8
pilot. I have bought three of them. Would have only been two, but I
destroyed one the first time I used it. CRINGE!

Sure HSS ones are cheap, but they are huge lumbering lumps by
comparison. This carbide one from Lakeshore is neat tidy, and very
precision designed.

Is there an alternative?

The tiny leads, and small pilot are what make this mill more useful than
others.
