Where to start! If someone asked me on my opinion this is it. Modular.
Pre 2007 I would have said integrated. However, things have changed. I was very close to going integrated but chose modular and it has been the best decision I ever made. I trained at the top schools at some point and came out spending £40k for 270 hours.
After finishing recently I now have the same piece of paper as someone on an integrated course but half the debt and not crippled by the interest payments.
The good thing about the integrated course is that if there are jobs then you are going to be fine, but now, very few jobs, you join everybody else in the pool and fight it out. I suspect that this will be the case for the sometime.
If you can genuinely afford £115k (including a type rating), and I mean GENUINELY (not just being accepted for a loan) go integrated. If not modular is the route to go by some distance regarding price.
(Sorry if the answer is slightly disjointed it is very difficult to summarise this subject I could write pages and pages on the modular integrated issue pro and con for either).
