 - haha yeah old news :p 
 but great for those who don't know
 - yeah, ain't news to me.. 
 but still it's worthwhile mentioning it for others.- i was in harveys the other day and there were these obviously dodgy 3m HDMI cables in the bargain bin for $70. wow! what a great special.. probably a measly $68 profit for HN on each one. - cheap 5m+ length cables can get a little dodgy. 
 you actually do need certain qualities(ie AWG ratings) to go distances- if you were building cables into the wall cavities of your house.. you'd obviously spend a bit more.. do some research etc. 
 - Haha hate to say this but I didn't know about that =) 
 Thanks!
 Feeling so outdated xD- Bought a 3m HDMI cable not so long ago for $60 from DS… now feels like I got ripped off! 

Is there anyone out there that DOESN'T know this by now? :D
