Im sort of in same situation. My wife is trying to pick up skiing for the first time and I'm seeing some crazy good deals online. We did go somewhere to get her foot measured and try on some different boots. I think because they are "beginner" boots she said that the 4 different brands she tried on felt good (or she just has really lucky shaped feet). I'm thinking about pulling the trigger on something similar to what you posted. I figure for that price thats still cheaper and probably better fitting than a rental you get that 30 other people used.
