I ordered the Sky-Watcher EvoStar
I ordered the Sky-Watcher EvoStar 80ED the week before Christmas 2020, fully expecting it to arrive in late January 2021 based upon the indicated delay on OPT's web site. I was pleasantly surprised when is shipped the following weekend and I received it on December 23, 2020. Always contact the seller that you are buying from to get an accurate estimate on availability and ship dates.
