Hi,
I went with Adventure Peaks, and couldn't fault them.
Our guide quickly sorted any problems - even down to getting us to Lukla on a helicopter with some Russian Geologists when there was a huge backlog of passengers waiting for planes at Kathmandu airport after a spate of bad weather. He also sorted out medical attention for me when I became ill. Feel free to email me for more info.
