I've heard nothing but compliments about those guys, yet to deal with them myself (I keep finding cheaper stuff on Ebay).
As for shipping, and taxes, etc, you shouldnt be worried with those, unless you're expecting something in excess of $1,000AU or if it's shipped courier mail, (or anything other than Postal Service).
I recently had 4 boxes of Finest come thru via Surface Mail (still hate Surface Mail) and it was about $600AU worth of products, and it arrived at my doorstep...
Good luck, let us know how you get on!
