The Ninja DS has great compatability of roms , features a build in program which can connect to a server to get files , and has built in media servers.
It's the cheapest slot-1 device and its the only Slot-1 Device which takes SD cards , SD cards have a very low price and are Way cheaper than micro SD cards.
The Ninja DS has quality , and makes the cheapest slot-1 bundle if you compare the prices of buying a slot-1 Device with 1-GB memory.
SD memory goes up to 4 GB.
The only downside is the size of the ninja DS.
And for those saying the ninja DS is to expensive, its cheaper than a M3 and its way Cheaper than A DS-Extreme , which official price is 120 dollars
for that amound of money people can buy a Ninja DS with 2 GB of memory , and I can tell you , on my M3 I find 1 GB not enough memory to keep my files and I have to delete stuff I actually liked from my card just because there is new stuff, so 512 MB is nothing to me.
Buying A DS-Link might be a good option cause its only 50 bucks , but you will have to have a flashed DS or buy it bundled with a MK4 mini , which will make the price higher.
