Hey mate, a lot of people on this forum are anti-cadetship for various reasons, so expect the majority of the comments to be negative.
However you need to do whats right for yourself. I've got a mate who is just finishing the Ab-initio training and I can tell you he worked bloody hard for it - because as well as doing your flight training, CPL subjects, ATPL subjects and MECIR you also have to do a UNI Degree and attend lectures at the same time. I don't know how he found enough time in the day to get through it all in the 13 or so months he's been at it....
It's also not just a pay to get in scheme like Joker 89 says (although it is very expensive compared to regular GA training), it's pretty competitive for the interviews as well.
Good luck, but if you get in be prepared to work your balls off......
