You could get a 1GB N-Card and an EZ-Flash 3-in-1 from Dealextreme.com for less than $49 with free shipping. You could get the 2GB version (I think it's a Firelink, same thing as the N-Card) for about $12 more.
You could get a G6DS Real from realhotstuff.com for less than $70 shipped, and the 3-in-1 from dealextreme for $19 with free shipping.
You could get a CycloDS Evolution and a microSD card for just a bit more than the G6 Real.
edit: You could get a Chinese G6 Lite from dealextreme for $45 with free shipping.
Dunno about dumping.
