Here you go Mike... Brett at Divelife
Apeks XTX 40, XTX 40 octo & free triple console RRP £525 - DiveLife - Scuba
I wouldn't go for a DS4 unless you intend to go twinset in the near future. A DST is designed for the job.
XTX40/50's are superb regs and will see you from beginner to deep tech.
Leave the computer on your wrist.. put it in a console and it'll get bashed about and be a pain to monitor..
have fun... good luck
I see your up north... Deep Blue have some good deals.
