Hey Neversaynever, I'd say between 3,500 to 5,000 max grafts ( It's just a guess, but I don't think it was anything more or less).
I've only been to the UK twice, the first time involved about 3 1/2 full sessions and the most recent one involved about 2 1/2 to 3 full sessions ( The sessions span over a few weeks). The second trip was for personal touch ups because I've got some free time and I wanted to get it looking it's best entering into the new year.
Spot on, the hair clippers for me any ways, doesn't cut it short enough and sometimes it doesn't cut it even. I can pretty much use the Remington's and do an almost perfect job with just a mirror and my hand.
Honestly, the price of HIS+food+tickets+ accommodation +PS3 games+extras is a whole lot cheaper than getting a hair transplant, which only leaves you feeling empty because you expected to have a lot more coverage. The only pain is the flight, it takes about 24hours to get to the UK and it takes about a week to feel normal. Overall, the HIS treatment has been money well spent and it comes at a small price when it allows you to be as free as a bird. ;)
