I own the Vortex Razor 16-48x65x, and I really like it. It has worked great for me. But the comment above about comparing it to Swaro is accurate. It's really not a fair comparison as the Swaro is over double the price, so it's apples to oranges.
If money isn't the deciding factor, get the Swaro. It's a better quality scope when placed side by side with the Vortex. If the money were not an issue, and I was looking for a scope to pack, I think my first choice would be the Swaro STS 20-60x65 scope. If money REALLY were not an issue, I'd go with the ATS (eye piece and lens come separately) and get either the 85 mm or 95 mm lenses in addition to the 65 and just swap the lens out for different uses.
If you have to be concientious of the price, the Vortex is a good way to go. Like I said, I've liked mine.
