Justin,
Please don't take this the wrong way, but reading this post, I have to ask what you plan on doing with a dovetail saw right now
? If you don't have a workbench yet or a vise or other way of holding your stock, you won't get much use from a dovetail saw. You won't be cutting any dovetails for a workbench, at least not the kind that would require a small dovetail saw like you are talking about here. My advice is to focus on a project (workbench?) and acquire only the tools you need for that project right now. Don't worry about what tools you will need later. Your future projects will determine that and you can get them then. If you need to build a workbench, you need a bigger saw, not to mention marking gauges, a square, chisels, etc., long before a dovetail saw.
Don't get too sucked up by the tool acquisition bug and forget that you also need wood and a place to work. Before you know it you'll have a bunch of tools you can't use, even more that you will later find you don't really need and others that you find you will need that you don't have because they aren't real flashy like super tuned smoothers and premium dovetail saws and therefore don't get the print that the fancier tools do.
I can't stress enough to focus on the project and let it determine your tool needs, not magazines, internet forums and the like. I speak from experience
