It is actually good to carry two different anchors. Sometimes you may not be able to grab the bottom in some areas with the primary anchor.
Rocna is a good anchor, as is the mason supreme. The bruce is a favorite of a lot of different cruisers.
I bought my Lewmar Claw Anchor (same as a bruce) from West Marine for less than $100. I then added 30 feet of chain to it for a descent price. It has held in some strong storms.
According to Lewmar, boats about my size can get by with a 22 lb anchor but I went to the 33 lb for extra hold. It also sits perfectly on the bow sprit!
