I have Dfritmasters, Titelines and some homemade ones with the PVC and the 45 on the end.
Here is how I would rate them;
Driftmasters are good,strong and will last a lifetime but they are not adjustable for angle. $15 each
Titelines are good but not as strong but they are adjustable for angle and pivot. $20 plus each
PVC iis cheap and it will get you by but once again the angle is not adjustable and it will break over time when exposed to sun. $7
My brother has the ones Cabela's sells and loves them. They are totally adjustable and appear to be made to last but they are around $35 each.
