Some pics from my
blog. Not a huge amount in the way of comparison, but there's a picture at the bottom of them next to a GW Sentinel, which might help.
As has been mentioned, they fit in fine with other ranges. I can try and take a couple of comparison pictures of them against hasslefree, copplestone, GW, and Reaper (not sure I have any painted Infinity) if that would help.
Definitely worth an order
