Best tool for buidling and maintaining a Win 7 install image

[pctech2012]

What tool is currently the best for building slipstreamed OS images as I want to roll in Win 7 updates and drivers and don't have the time to do it manually.

It is for my own use so that I have a working image for my new system, I will be starting with a copy of the files from an OEM DVD.

I've used nlite before, does that still work ok?

nlite was for 2k, XP and Server 2003, vlite took over for Vista but there's nothing from the author(s) for 7.

RT7 is considered good for slipstreaming 7 installations.

I use a bunch of batch files that makes the process mostly one click. RT7 is okay, but I've found it a little buggy sometimes (certainly when rebuilding images)
