Well, I had the same question and bought SKYRC T6755 because it was available for delivery in less the 24 hours. Ordered on Sunday and picked it up on Monday at the store here in Mexico City and that is quite rare to have such a service.
Tested it on Monday and today and it works as expected for my needs. Storage charge, Balance charge etc. etc.etc. etc. I have only LiPos of 2200mAh 3S and 25C chargeable up to 2C.
It came with a cabfor chargin the LiPo batteries and I adated the Cabe for using it ti charge from a car battery. It has a XT60 connector and I added 2 crocodile clamps for a car battery.
