It will almost certainly cost as much if not a bit more to build your own,for example take the Berkley Dropshots,full Fuji hardware including alconite guides on a decent blank all for round the hundred dollar mark,added to this if you haven't done a few your finish probably wont be as good as the mass produced job.It can however be satisfying to build your own,if you were to go this way any tackle shop worth there salt should carry an extensive range of all that you need.
