Got one back in April - awesome bike, love it to bits. Spoilt somewhat by the mudguards and pannier rack that live on it, but it wasn't bought to be raced.
Commutes just fine on the Small Block 8 tyres - bit draggy on road climbs but not too bad, and I've put fat slicks on occasionally for wet weather road rides. Very competent on towpath surfaces which is most of my commute.
More comfortable to ride than I expected tbh. Think the longest ride I've done on it was 65 miles - maybe 1/3 of that was off road on the High Peak and Tissington trails. The 30 tooth cog at the back came in useful riding from the ford up to Tissington village.....
Being finicky I'd have preferred a slightly wider set of bars, I just never use the crosstop brakes, and they'll be going as soon as I can be bothered to put some more comfy bar tape on, but I've lasted this long in stock set up so it clearly isn't a huge issue for me.
Size wise, I'm 5'9" and a little bit, and got a Medium 52cm frame, which fits fine - the sticker on the frame does show it as being intended for people up to 5'9". If you are near Nottingham /Derby and want to try one for size my email is in my profile, but the staff in the Nottingham Evans were pretty good at sizing me up, if you can get into one of their stores (I know they vary!) they will get one in for you to try.
Edit:Think the cheap frames are non-disc version?
