No one can tell you what is right or wrong for you to have in your personal collection. If that's what you like, then go for it... Just make it clear it's a TT if you decide to sell it on 8)
I can't believe so many have them and enjoy them in their collections. They are fake, end of story. They may look the part on display, but so do repro weapons.
I wouldn't buy one now for a focus or otherwise knowing what I know. The danger is it will encourage more fakers if people start collecting them. I do have one though, it's a 65 back Chewie and the first MOC I bought (as an adult). I love it and I'll be keeping it. It reminds me of when I started collecting, my naivity and is part of my collecting journey. It's an important piece to me.
