I'm very happy with my Jetstream supply, which is 28 amps peak and i  
think 25 continuous. Its fan is very quiet and I haven't noticed  
appreciably more noise than with other supplies. Besides your standard  
binding posts, there is a cigarette lighter plug on the front and low- 
current spring terminals on the back, the sort of thing you're likely  
to see where you connect stereo speakers to your stereo. The 28-amp  
version costs about $80 plus shipping. They also make a 45-amp (peak)  
version as well. Among he best prices I've seen for these has been  
from R&L Electronics. This supply (the 28-amp version anyway) is very  
small and lightweight. In fact, I'd say it's perfect for an emergency  
go kit as far as size and weigh go. I can defnitely see slinging this  
and a K2 in a bag with some sort of portable antenna and going. .
