I asked the same question just last month. Everyone was really helpful but most of them are close to the city! check out the link http://coffeesnobs.com.au/YaBB.pl?num=1183254260
I also bought a kilo off Go Barista (one of the site sponsors) who delivered it the next day which was just way to easy.
I did buy my last batch from Merlo because like you I used to buy from them but ground! Now I can get the good stuff from them.
Good luck and have fun with your new machines :D
