driveshaft

Currently on my second rear driveshaft (re-tubed front from an auto xj) and slip yoke is worn again causing vibes and I am thinking its a good idea to upgrade to something a little better.I am looking at a coast driveline cv style for $289 plus shipping to canada, seems pretty reasonable, anyone ever had anything bad to say about them or their product?

Went with this one http://www.northridge4x4.com/proddetail.php?prod=COAST-1310 . The slip yoke wears out pretty quick using the stock front shafts, nothing against tom woods but, the price was very high when shipping to canada, and for $279 shipped I can't complain. I was just looking for input on the coast one
