Not necessarily a recipe request, I always do my corned beef in the crock pot. But if you have other ways to cook corned beef, I'd appreciate a recipe.

I'm more interested in the different cuts of beef. I tend to buy the cheapest, what's on sale.
This year I bought the "Point Cut Brisket" on sale for $1.99/pound.
There were 2 other choices at $3.99/pound and $6.99/pound. (I don't remember the type of cut they were.)
I know the cheaper cut is fattier. But in a crock-pot it is tender and delicious. I skim off the fat before adding potatoes and cabbage.
If I bought the $6.99/pound beef would there be a major difference in taste? Would you need to cook it differently? Would putting this cut of beef in the crock-pot somehow insult it's flavor? Is this the type of cut that should be roasted? (I've never roasted corned beef . . . is that yummy?)
Just wondering if getting out of my rut of buying the cheapest would be worth the extra cost.
(edited to correct spelling.)
