I've got the wii via singnet bundle, so far no problems.
I've yet to get extra controllers and games though, AMK Hub has
some good bargains of those popular game like Super Smash Brothers
Brawl, bundled with 2 inferior games at 99 bucks.. typically the
Smash bro will cost you maybe 79 bucks.. so it's like.. at least u
pay a bit more get 2 more games.. :)
I've used my miniSD with adapter on the wii.. also no problem
with the pictures, haven't try video nor music though..
I've also linked to the internet via wireless and bought wii
points too.. just set the country to US in order to use the wii
shop, news channel, forecast channel, etc..
yeap. like that lo.. 
What do you need to connect up to the internet on Wii...? Do you
need router or any other accessories from Wii?
What internet subscription are you currently under...?
