Help finding corner shower unit?

Anyone know where to find a good corner shower unit in the Midwestern US? Looking for a 38-42 in neo angle or rounded front corner unit, trying to figure out what it's going to cost total to get the walls, base and doors. The home improvement sites are not very helpful, because everything either says walls sold separately, or base and doors sold separately. Seems like they would have links to show you which pieces go with which. Sales people are about as helpful, directing you to look on their website for anything you don't see in the store.

I'd just like a shower that we can install and use. Don't want anything fancy, and I'd like to not spend my kids college fund to get it!

So help me out, if you've been there and done that, let me know what you bought, where you bought it, and whether you like it now that you have it.
