The 1505A is much less stiff than the 1694A and yet easily capable of 200ft for HD-SDI. Any longer or 3G, I would use a DA.
The 1694WB has identical electrical characteristics to the 1694A, but is designed for direct burial and underground conduit runs. Perhaps due to its gel filling (the water block) I find it slightly easier to work with than the 1694A.
BTW the plenum version 1695A is not recommended for portable use -- while it is a smaller diameter cable (thus easier to work with), its jacket is quite thin.
You will save a lot of money making your own cables, but the tool is not cheap. What you'll need for the 1694A (and Gepco's equivalent VSD2001):
King KTH-1000 crimp tool
King KTH-2325 die
King 2065-10-9 BNC connector
