Cheers for the feedback...
Looked at a Framemeister, expensive and I need to ensure this isn’t just a fad I quickly get bored of hence why I thought I might try the Retron. If I like it then I might expand and buy a console or two and consider a Trinitron CRT or a Framemeister, probably the Framemeister, convincing the wife why I need to bring an old CRT TV into the house wouldn’t be easy.
