Slot-2 devices

Hello! I'm new here, and I have an outdated r4. I'm planning to buy CycloDS, since I heard that is the best, so then I thought, what the heck, why not buy one of those slot-2 devices too? I was just wondering which slot-2 device is the best. I searched the forums for the answers, but all that came up were questions about whether you can play gba games directly from slot-1.

EZ-Flash range/3 in 1.

Thank you for moving the thread. :) So, the best is called EZ-Flash range/3 in 1? Is that like the official name?

It's the EZFlash V 3 in 1http://www.dealextreme.com/details.dx/sku.2967

http://www.realhotstuff.com/expansion-pack-size-p-212.htmlI do not believe the thin NDS Lite model will fit in the NDS Phat. The model for the Lites are too small.
If you are using a CycloDS, you should try to find a non "Plus" version of the EZFlash 3 in 1, like in the first realhotstuff link.
The CycloDS still has a couple bugs with the Plus version, it's nothing major mostly dealing with the NOR mode which is not used very often, but it works just fine with the non-plus version.

Ok, thank you very much for the help. :)
