low power AM transmitter-any recommendations?

Thanks for the ideas on the transmitters!

Paul, that SSTRANS kit looks like a nice little unit. Lots of great features for a reasonable price. I'm seriously considering one of these, even though I already have the compressor as part of my low-power FM setup. I really like the antenna tuning built into this set. I just wish it was easier to change transmitting frequency though. I'd rather not have to open the case to set freq. But this seems to be the norm for most LPAM transmitters. I'm also wondering about noise problems with the unshielded plastic case, and if this will be a problem when used in close proximity to my LPFM xmtr?
