Scarf; Some of the instructors are very good, but be careful about assuming all are when you have nothing else to compare it to. Some haven't been valid on radar for over 20 years and some are contracted back in because no one else wants to do it! Those who hold validations are excellent instructors. But there's a few who have a nice little earner going on, who by all accounts were a bit ropey when valid!
The problem with the 10k is it's an extra pressure you don't need. Plus I've heard some people need a part time to job to live, that cannot help you to focus on the course. Plus how do you afford to let your hair down and wind down at the weekend?
