Hello all. I'm looking to invest in a new tripod, but have little knowledge about what's out there. Currently I have a cheapy from Walmart, though I'd like a little more flexibility with a tripod especially for my new Nikon d300s. Looking to get away from a panning/tilt head. I know a bit about Manfrottos, not sure what other brands are around. What do you use? Or what do you recommend? Thanks!
