Yep, Sinclair would be my number two choice.

  Robert,

   

  I would have to agree with Chuck, the TXRX brand is hard to beat. Now you 
want isolation, Just keep in mind that the noise floor is rising and what you 
purchase today will not be the same as if you purchase it in five years. Bigger 
is always better and at sites today you can't go wrong with going over kill on 
the filtering. If you get the standard 4" cavity BPBR duplexer. You can have 
them add a extra band pass to both the TX & RX side for some extra out of band 
protection. When you get the duplexer add a TX isolator if your repeater does 
not have one built in like the Motorola MTR2000. Anymore us hams need to keep 
our stuff cleaner than the commercial guys. For the most part a lot of us do so 
but there are a few that really skimp and make it hard for the rest of us when 
dealing with sites.

   

  If you decide to go with Sinclair here is one on EBay that looks new and will 
perform as good or better than the TXRX and is just an option/comparison in 
duplexers.
