[Repeater-Builder] 2 Meter Repeater Duplexer . . .

[Lot]

Hi Everyone, 
   We are setting up a project in Manila and would like to ask some help with 
information about a good repeater duplexer. 
I saw one in Ebay, (Sinclair Q2220E VHF BpBr Repeater Duplexer).
Is this a good type of duplexer and would work on a typical repeater setup? We 
will use it on a VXR7000. The Repeater Frequency will be at 144.880 - 0.600. 
   Any information will be very much appreciated. 
 
Thanks!
