I'd suggest a Tohtsu CX-600N on the output and something smaller on the 
input, or, alternatively a CX-800N which is double throw.

Check out Ebay HenryRadio are setting some CX-800N relays and RF Parts 
appear to have the CX-600 on offer.

There are a lot more 24/26/28V relays around cheap than there are with 
12V coils - the latter are a premium.  The difference is sufficient that 
all the relays on my home station and contest stations are 24V.
