Modchip question

[StarChild]

I personally dont know how to solder nor know anyone that could at the moment. My question is, the no solder modchip / swap magic disk combo (I know its probably a pain to swap disks all the time, but if I dont have to solder, fine for me!)... can it play mostly all games including japanese games (imports)? Is there any things I should know before buy this? Pro's Con's would be helpful :)

Thanks guys !
