CP2009 I wont comment on the COS any further as you probably have it right in front of you but my understanding was the medical, schooling and housing were all benefits of the DESO package but I stand to be corrected. Like I said good on you and enjoy it pity its in ADL though
FL999 I dont know your personal circumstances but provided you go into this with your eyes wide open which you seem to be by doing the maths then I have no problems at all. What I was saying is that your finances have to considered very carefully and certain people saying I survive on 500 a month didnt give that credence, neither did the option of becoming a hermit for the first four years. Remember you work to live not live to work.
Otherwise I wish you well and hope they contact you. I had a good time at the interview and met a lot of nice people there. Maybe I'll see you there one day.
Enjoy
