I had a SingleHop server for around a year, I had an excellent experience with them. their network is very good as well. I can't recall any downtime, support is very good with them too.
They do charge more then most providers of their size for a gigabit port upgrade.
Other then that, in my opinion you can't go wrong going with singlehop.
