Difficult.
I -suspect- that it is. Price is usually an indicator in one direction only. Buying a clone of a $100+ product for under $20? Definitely a Chinese clone. However, the reverse isn't necessarily true. Buying a clone of a $100+ product for $40 might be, or might not be. That's a nice battery he's offering (if it's authentic) but if you get that one, throw that charger in the trash immediately and get you a good charger!
Personally, between the two, if I were in the market for a copper caravela clone, I would buy the first one and take my chances. That's me. It seems to me that either product could have an issue, roughly equivalent risk (which realistically is only in the 5% range) and better price.
I'm not saying you should, but that knowing myself, that's how I would think.
Well, I agree with you, however I'm talking to a dude from ebay that has that patriot calavera combo and he's letting me pick any other atty that he has, which is nice of him, so I'll most likely get from him since it builds some trust between seller/buyer
