Venom Pro4, HiTech DRX1 Mini, SkyRC S65
 

These all look to be virtually identical with just slightly different covers. I'm thinking they all came off the same assembly line. Is there anything to recommend one over the other, or just grab whichever is the best deal right now?

Thanks.

Good eye, and yep... SkyRC is the OEM for a few companies. Add Horizon Hobby's Dynamite chargers to the list as well. I had a Hitec X2 AC Plus charger...same as the SkyRC D100. They are not the only ones who do this. Sometimes you can get a better deal buying the OEM, and not pay for the more popular brand/"sticker". UltraPower did rebrand some of their chargers and slap a Reedy name on one of them...along with 50% more cost.
