A very useful set of comments and website!
I have used two of the three in Miami, yes, they changed the machines. $600 limit per visit, ID required. I believe that "Subsequent Visits" have somewhat less onerous requirements, as the machine (system) remembers who you are, you enter your phone number and PIN number.
I will have to re-check the premium, it WAS 9%. 13.4% is distressingly high (I did not even bother to do the arithmetic when I last bought BTC).
The newer machines are more robust than the older Lamassu's.
As I see from online info (if you click check online button). Limit is $600 per purchase, and daily limit is $1000, so I assume you can do a second operation right after the first one for $400 more.
Didn't know they ask for ID from the very beginning, this is not usual scenario. However, operators are free to do different verifications based on their KYC/AML compliance program.
Regarding fees, this one (13.4%) is calculated online based on price feed and is calculated against to BitcoinAverage. I use the same feed for all machines to make fees comparable.
So sometimes operators might advertise different rate in case they use different feed, e.g. BitStamp, Coinbase etc, BitRocket uses by the way Coinbase feed as it is seen on the site, but I calculate fees myself. Will be good if you could check it at a new Satoshi machines and update in case it is wrong.
