[Elecraft] K3 power supply

I've been re-considering my power supply. I'm using a Heathkit PS 
which is a 20 amp linear supply. I just looked inside it and it's 
definitely showing the effects of age. It hasn't been used in quite a 
long time as I've used a TenTec supply with my Corsair & Omni since 
day one.

Ihave a few things runing on 12V and they probably draw 2-5 amps on a 
steady draw. With the K3 I suppose my requirement would be 22A so I'm 
looking at a 27 or so amp load. I'm currently using wall warts to 
supply the 12V peripherals and would like to unclutter my station and 
meet all my "12V" needs.

I'm considering several power supplies & looking at eHam reviews I 
see Jetstream. They have high reviews and make a nicely affordable 
28A for $79 and 45 amp power supply for $149. 

Anyone have any experience with these & the K3?

I'm thinking the larger one might be a good choice in that the 
components wouldn't be stressed at my station. I do prefer low 
stress...

Any thoughts on these supplies?

Hope Santa was good to you!
