SNMP Trapping Question - What is Best Tool for the Job?

Hello;

I've gotten devmon to work on my current Xymon setup; the only drawback in my opinion is lack of device support in devmon.  I'd like to roll-out something else that would allow me to receive SNMP traps from a device, and send out alerts via Xymon.  I'd also like to be able to use WeatherMap,  and of course want to make the three of these work together as seamlessly as possible.

Thank you all in advance,
