there is a 4 port charger currently called quattro available via HK and several others (Imax, Dymond), it is 50W per channel.
The next 4 port one, branded as a turnigy (HK's instore brand) is supposed to come out in a week or two, w/ 100W per channel. They claim $80 for the charger, my guess is it will end up being closer to $100, plus $20-$30 for shipping to the US. Still cheap, but you would be buying a newly designed, unproved charger, w/ very expensive return shipping if defective. Also, the alcready said the outside case will be plastic, how many internal corners will they cut to save cost?
The hyperions are great, but costly, I just don't see how with technology improving daily charger prices stay static (or increase). Just my opinion.
Just reread and saw your were asking for links....
here is the HK quattro....
