Neokey to neo 2.2 or origa?

[telephone]

I have a neokey, or i guess its also called sbox maybe too? anyways its a external modchip and i assume it doesn't load dvdr backups from what i've read so i need a new modchip. i have a US (v5 i'm pretty sure) ps2 and so if i got a new modchip would i have to unsolder the wire i already have in there? is that possible? and which modchip do you suggest, charlie or whomoever for booting dvdrs? and is there a place i can buy the modchip from in the US that will also install and uninstall it and the wires and the wire i already have in? thanks a ton!
