I had a Turbo Express for a while (long after it was gone from the market though). I got rid of it too because of the low quality screen. By the standards of the day it was an incredible screen but I just find the screens of all those old portable systems hard to look at now. I would rather play the games via emulation on a screen that is larger, has no motion blur and better contrast. I still have a Lynx but I haven't played it in ages.

I had an Atari Jaguar but got rid of that too. I kind of wish I had kept that one though. There weren't many good games for that system but there were a few.

Speaking of Atari, this looks interesting: https://atarivcs.com/
