I really like mine too. If you're paying in £, like I did- look at dv247, got mine for £245 in the b-stock area. There's nothing wrong with it at all, and it's near half to price too. I really, really like it. It sounds great, plenty of options to play with, a whole variety of tones can be created. Plus, connected to both my cabs it's incredibly loud.
It's a great buy, can't fault it at all. Also, not to hijack your thread but I asked about this head not long back too. Might be worth checking out my thread. Plenty of opinions and stuff in there. I'd link, but I'm on my phone

search tool should find it pretty easily though.
Edit:
Got to a computer, I'll save you a job:

Also, you might find the 15th post here really useful too.

-Credits to BackToTheGroove for that post.
There are other threads, there's also a review in Vintage Guitar magazine that can be found on the TC Electronic website.
Hope that helps
