Advice please - simple stable cart required

[setspeed]

Hi, i need some advice on choosing a flash cart for use in a DS Lite for my 4yr old. We have not yet bought the DS Lite, but i want to download ROMs to play on it.
I have done a bit of research, but having never used any cart or even a DS i feel i need more help than just reading reviews etc.

Basically the cart needs to be simple to operate (not many steps/options to choose once loaded), preferably cheap, fast non-laggy interface, and not easily broken by a 4yr old taking it in and out of the NDSL.

I gather the best carts around are the CycloDS (expensive) and the SDOne (not simple/user-friendly).
I have considered the TTDS as it's cheap but the lack of ROM file sorting kind of turned me off.

The cart really only needs to be able to play games and thats it.

Can anyone suggest which i cart i should go for, or suggest another?

THANKS!

R4 is no more supported.The fake ones are mushrooming the market.
Get Acekard2 with best GUI and next to DSTT in price.You can get it from dealextreme.It is cheapest over there.
