I was around $1500 - You can see the price breakdown here - http://www.homebrewtalk.com/f51/jeeb...3/#post4113262
But I didn't wait for sales or any of that. And I did not do it over a long period - maybe a month and a half - just on the weekends. Also it was my first woodworking project ever - so I had to buy tools - which are NOT included in the price.
That being said, its doable for much less you just have to be patient.
I concur with purplehaze on the faucets - go with Perlicks the first time around.
