Came across this thread glancing down the list. I have just come to the end of my three year City and Guilds Course, having found an apprentice placement over 3 years ago. I would say, from someone just coming out of it, don't be put off by the apprentice route. Yes four years is a long time, but if you can get a placement, get your head down, crack out your NVQ while your doing your tech certs and you'll be down in just over 3 years. I spent my whole three years sitting in with full-timers who worked in tescos (no dissrespect) but i ended up teaching them.
With time comes confidence. Something that you won't have if you stutter through a quickie course, then come to the end of it and get asked to install and test, and end up making mistakes. Some of the guys have come and gone since i was there, are more qualified than me, but i have much better basic knowledge than them, and theres not many jobs that i go on and don't know where to start. 9/10 of the employers after will then ask for 'time-served' applicants.
But anyway there's a little insite for you, best of luck anyway
