I received my DSi (black) plus 2x Acekard 2i units today.
Works perfectly, arrived EMS shipping took exactly 1 week to get from them to me (based in UK).
He said sent Friday, but tracking system showed it did't go anywhere till Monday morning, so 5 days... not bad at all. No tax charged or anything (no invoice inside box).
Quick comments: DSi is gorgeous. Love the matt finish and rough texture, new screens (when compared side by side with DS Lite) seem much bigger than the .25" inches increase or whatever it is would have you believe. Quality of screens was an interesting one; no dead pixels, but appeared to be overly 'green' biased in colour.
e.g. Professor Layton appeared far more 'red' and saturated on the DS LITE. It seemed more... arty. However, when looking at a book page the DSi appeared to show the paper in a more natural colour. Was finding it diffcult to decide which was more accurate.... so loaded up Prince of Persia The Fallen King. Wow, massive difference between 2 units. The DS LITE was far too pink (again bias towards red). His costume in the intro was perfect white on DSi, but on DS LITE was un-naturally coloured.
Acekard 2i seems to be working perfectly, no issues whatsoever thus far. Odd jerking issue in PoP but i'm pretty sure that's the game itself (only occurs in the middle of a jump).
