Apple,
On balance I would say probably go for it. If you are the type of person that will kick himself in 20 years time for not trying and you currently have the funds then do it. The modular route is probably best and if you can keep your current job on a part-time basis then that's even better. If you do it that way, it should take you about 2 years or so. Full-time modular courses should take the same time as their integrated equivalents, generally a year to 18 months.
Make sure you have a back-up plan if things go pear-shaped.
Best of luck!
