Looking for a Decent .NET Forum

I’m looking for a decent forum built with ASP.NET. I love the functionality of vBulletin but they don’t make a version for .NET. I’ve also found InstantASP but it seems clunky compared to vBulletin. These are my priorities:

  1. Need to be able to install on my server (not hosted solution)
  2. Easy to skin or adjust the template
  3. We have a budget, but it’s not $10k

Any and all recommendations are appreciated!

In the rare instance that someone else finds this thread in search of a .NET forum application… I went with InstantASP because of the number of features it could offer out of the box. That being said, there is a huge market for .NET forum software.
