we do a 600ss as a dmarc into every house. we care the mccown replacement cards now for any that need replaced. We used the beehive ones back in the day but they werent compatible with the 320 at the time so we did the 600ss. will probably migrate to mccown tech again since theyre not kidney expensive and pretty universal
