ISA vs Novell BorderManager

[Denda]

Hi All -
I'm looking into replacing our Novell BorderManager 3.7 with ISA 2004. We currently use Radius for remote access, proxy server & SurfControl for website blocking and that is about all that we have on the Border server. We are planning on slowing converting our Novell 6.5 network over to Microsoft. I'm wondering if I can get some info from anyone who has already done this.

Are you happy with the switch?
What did you gain with the switch?
What did you lose with the switch?
Any unexpected gotchas surface?

Thanks!

Tried asking this convert-question in "Microsoft: Windows 2003 Server" forum? It has quite little to do with ISA 2004, so it might be best asked there. Apart from may be moving from BorderManager 3.7 to ISA 2004... But this experience, i don't have. I've been using ISA since version 2000
