regarding BCDs, there's a lot going for the buddy range and people rightly recommend them. however, they never felt right for me and there are other BCDs out there. i dived with a scubapro BCD for 7 years. it never let me down and i subjected it to quite a lot of abuse including sticking a twinset on it for a while
from what i've seen, cressi BCDs are well made too. if you get a chance, try both the cressi and buddy for sizing and feel.
at present, i dive a single wing which i put together for well under £200. i imagine they'll be a shit storm if i recommend the same to someone who is just starting out, but just a thought
