Single row panoramas have always seemed to thwart me. Either the scene was never appropriate or they wouldn't stitch for one reason or another. After getting the stuff I needed to establish the nodal point on a couple of my lenses, I decided to give it another go from Kerry Park.
First, and most importantly, know what genres of photography you enjoy the most and if that genre requires a tripod. Then, buy the largest, highest quality tripod you're willing to carry that fits in your budget. Specifically in that order; do not put budget ahead of any other aspect of the tripod. If you go too cheap, you may very well end up with a tripod that meets none of your needs when you're forced to replace it due to instability or fragility. The adage, "buy cheap, buy twice (or more)" applies here.
As much as I like Gitzo as a brand and the quality of their products, some of their stuff just isn't as good as others. Take for example their leveling base; Gitzo features a large lever for tightening a head to the base and a handle borrowed directly from their sister Manfrotto's lineup. Instead, I got the series 3 leveling base from Really Right Stuff. It's lighter, has a simpler attachment system with no silly lever and a much sleeker locking handle with, get this, a gear hook! That hook alone is almost priceless, allowing me to attach weight for stability when I'm not leveling the head, ending any need to swap back to the flat top base. Back into the box that can go.
