Another vote for Rush Hour. I didn't make it to Outland in time (remember that shops in .nl have shorter hours than us Yanks are used to) but have heard good things. Love the Outland record labels over the years -- distinguished by the outstanding Dadara cover art. (I wanted to pass on a good display of that but his web site seems to be down now).
Here's a quick photo guide to a couple Amsterdam shops: http://www.freestylegrooves.com/docs/gallery/ga_adam1.htm fred
