psx modchips vs. game enhacers (help)

[draino]

I was wondering which of the two i should get. I want to be able to play backups of games that are new. Should I get one of those stealth modchips or a game enhancer. Whats better. Also wheres a good place to get either of the two. Also do the new stealth modchips get detected by anti-mod games cause someone said they did i think.
Thanks
