I started such poll and it went completely ignored. This is something that defintely has demand and for people like me, who require the htg 220v version, this can be the solution. I think it'll be quite easy for MD to negotiate with US based Datavac.
I feel you on the ignored poll thing. I have three, they're at the top of the list one day and go straight to the bottom. I only start polls that haven't been already created, not totally gaming crap products oriented and affordable. They just get ignored. I don't feel as though Massdrops system of which polls are listed is fair. Popular polls just stay at the top but items dropped keep getting dropped.. It's several weeks and now the audiophile section is just "go here to get these few items for cheap"
I've had the ED-500 for something like five years now, using it every few weeks in that time, and it's still going strong. I can't recommend it enough.
