Try the recipe section of this website. You can find a lot of frostings and look for one that will suit your tastes.
They can all get pricey depending on what ingredients you use.
If you use a recipe that has all butter it's expensive because the butter isn't cheap.
In my opinion the Wilton recipe tastes very greasy. The nice thing about it is that it lasts a long time and it doesn't require refrigeration.
Here's a recipe that tastes a lot better than the all-shortening one: http://www.cakecentral.com/cake_recipe-1948-Butter-Cream-with-real-butter-for-decorators.html
Welcome.... I see this is your first post 
Is the wilton one you are referring to the one with the meringue powder. I use the Butter Cream (with real butter for decorators) recipe from this site and think it's great. I use it because I really like crusting buttercream and it crusts well. Other than that I know that there are some. I know that recipes that call for Meringue can get pricey because it's not cheap stuff! The nice thing about crusting buttercream is that you can wait about 10 minutes and then one you can touch the frosting without it sticking, you can lay either a non-patterned paper towel (viva brand), or wax paper gently on top of the icing and either using your hand or a fondant smoother get your icing really smooth. Then you could use borders, etc.
I would say browse through some of the pictures and find a cake that you would like to try and then pm the person and ask how they did it. Or post the cake that you would like to try and ask for tips. Everyone here is soooo helpful!

I use the Wlton recipe but sub half butter and add fresh lemon juice instead of extract. I also leave out the meringue powder. I think they just tell you to put it in so you buy their meringue powder. I have never had a problem leaving it out. You can also get a really good deal on powdered sugar at Costco. They sell 25 lb bags of CH for real cheap!
BTW- The meringue powder is not what makes the icing crust. It is the fat to sugar ratio that causes the crusting.
