MICROTRONIKS
I heard they're also good but have a smaller inventory - and only charge $4 to ship up to 1kg anywhere in the country.  I don't know what's up with this company as their website has no direct contact info and when I ATTEMPTED to email them from their Contact page it didn't work and no one responded to my email and the phone number I found on the internet is just that constant fast out of service busy.
