Can you get these in Aus? They are not great to look at but work well, are cheap and stackable. I've got a couple of these and they are good for the money.
(UK price £23 == AUD 54 which is way more that the 35 target but is about as cheap as I have ever managed to get in the UK).
They start at about $15 USD here. Shipping to AU will cost as much uless you buy a full case of maybe 50 units. Look at this site. www.pricewatch.com you type what you need in the search box and it returns a list of vendors supplying the part sorted by price. Many will ship overseas many won't. One hint. You likey do NOT want to deal with the vendoe offring the lowest price and Do read the reviews of each vendors.
Edit: Just re-read you question. If you want firewire prices start at US$ 35. not 15.
well i wouldnt mind hose lego blocks 😛 but there just not my look, i guess ill have to look around more to find some, is there any brand names you would suggest, becuase my old one was a cheap no brand and screwed up
