The 1st and 2nd stages I picked up this weekend from CL for 50.00. The Octo I got last fall at a thrift shop for 2.50. Everything works great. I know nothing about them though.
The octo is a Prosub and woks better than any reg Ive ever used.
It would help if you would stop using photobucket and post the photos directly on ScubaBoard. Quite a few of us cannot see photos that are hosted on photobucket. All I see is a red X.
