Replying to Sachtler Tripods

I'm going to retire my current tripod soon and seriously upgrade. I've been looking at the Sachtler Ace and FSB4 aluminum and was wondering if anyone could tell me their experiences with Sachtler products and if this is the best tripod for the money. From the research I've done I've only heard great things about their products. If you can think of any better tripods out there for the price that would be greatly appreciated as well! Thanks!
