Thanks for the offer...I need my DC relays for heat bed and hot end still.
I followed the route of a 24v power supply which in hindsight was probably not the best idea since everything runs off 12v and I ended up getting converters for 12vdc. I thought I would drive he hot end with the RAMPS board but to get a 100w (40w hot end + motors, etc.) down converter is pricy so I ordered a second DC relay and a 24v heating element for the hot end.

Relay ~$4 + $1 for hot end heater.
