There's a rather beefy SPDT Daiwa that I've bought used that works 
well.  The Alpha-Delta SPDT and SP4T switches are pretty good RF-wise, 
but their QC is poor. I have several of the SP4Ts, and have used more at 
Field Day and CQP county expeditions.I have one that could NEVER have 
passed final test if there was such a thing -- the #4 position was 
missing -- and one position in another switch broke for no obvious 
reason.  I've also run into a bad switch on these portable setups.
