If I have to, I'll settle, but I'm sure there's got to be somewhere selling them for like $5 each.
Tip Size: Inside:2.8mm Outside: 5.5mm
5V 3A (more than 3A should be fine too, but must be exactly 5V)
I got one from eBay user "emtcompany". The model is CHI CH-503 and I paid $10. Be careful because it might not come with the AC cord. I happened to have a matching one in my big box of cords.
The tip size specs are from the auction description for the CH-503 which is currently powering one of my MI424WRs. Keep in mind this is for the older MI424WRs only, as pointed out above.
I just got my two hooked up from one end of the house to the other and it's working great! All thanks to this thread!
