Well, I'm getting a G6 Lite then.
Martin, I have noticed your posts before back when I was doing research trying to pick out my flash card. You seem to have too problems:
1. Your overly critical.
2. Your overly cautious.
Theres nothing wrong with being both. In fact, your only trying to protect yourself from getting screwed. But all of the discrepancies that I have seen you have with the cart aren't really that much of a big deal at all, and you are taking it way out of context.
The G6 Lite itself is a fine product, you won't have any problems with the GBA shell. The only way you could break it is if you apply excessive force, and it's your fault if you are that rough with it to the point that it snaps. The actual shell itself is supposed to protect the delicate innards, you'd have to have Hulk fingers to break it in two.
Instead of being so hard on the G6 Lite, you should be more critical and cautious in regards to where you'll be making your purchase. After all, they will the be ones supplying the G6 to you. If you are willing to put up with the price, Gamersection is a great place to go that currently has them in stock. However, Chinese and English versions are only different with the language, otherwise it's basically the same product. If English versions get inflated prices in the future, I'm sure you'd know which route to take.
