Nintendo DS Lite Flash Cart Selection

***WARING NOOB ALERT***

Hi everyone! I'm new to the whole DS Flashcart thing. I am sorta a PSP Vet. as I know the ins and outs of that system but when it comes to DS I'm kinda clueless:confused: Could someone help me make a decent decision on what to get? Here's the specified requirements:

1.GBA Rom Support
2.DS Rom Support
3.Possibly Slot 1 With No Passcard

Money is not really an object but the lower the better:thumbup:

Thanks to anyone who replys.
