Free Radio Cafe: Pirate Radio

Hi Folks! Been out of the game since 2006, and so much has changed since then it's crazy. First and foremost, all these damn inexpensive transmitters from China. Who'se got experience with these? How're the power specs (is that a real 25W or just BS)? There's not much info available but some 3-4 year old posts complaining that they give off spurious harmonics etc. But since? My guess is these things are only getting better, but I would LOVE some opinions before I spend my hard earned cash on a new set up.

thanks!
