The two big names are Meade and Celestron. Meade declared bankruptcy a few months back, mainly to avoid a lawsuit judgment. Either one is probably a good buy.
Everything is in short supply, so be prepared to wait.
I would go at least for a 6”, and get a goto scope unless you know the sky really well. Much bigger than an 8” and you aren’t going to want to move it around but the views are incredible. I have a 12” Meade SCT that weighs nearly 80 pounds, but really opens up the universe.
There are some great deals at shop goodwill.com with local pickup only in Arizona. Others are available for shipping.
While waiting for the perfect scope to be back in stock you can see a million stars using a humble,ceommon 114x900mm newtonian reflector.
