I am in the process of building one right now. I bought it as a father/son project to do with my 10 year old.
Looks like a great kit . . . only complain is that it is so small! Not much of a complaint. We have it together and I fixed up my son's cold solder joints on the audio amplifier, but am still not getting any radio signals. I need to take a closer look at our work on the RF part.
I think the kit is great, perhaps a bit overpriced at $24 without a case. I plan on building a case just to give it more of a home made feel. I think MJF sells a similar kit with a case for $30.
I'll post again once I have time to find the problem with my son's soldering.
