Any tube style Red Dots other than UltraDot anymore?

I posted this same topic about 3 years ago and wanted to try again.  Although I use Ultradots just wondering if any other options available.   Are there any tube style dots that are still available other than the Ultradot?  Thanks.

There's a bunch. Check out Midway USA or other sites.

Throw some shades on an H1 or H2.
