Hi,
A buddy and I have been thinking about getting a Poseidon Jetstream / Odin reg and we are pretty confused about whats the truth and whats opinion.
We'd like to know:

*Is it true that the 2nd stage is 'fussy' to tune?

Fussy? That's relative. You can make it work and even breathe easy but getting rid of the shudder in shallow water is apparently a game for the exceedingly patient. You need to see shallow water shudder (or chatter) as normal for these regs.
*Is it true that their are NO working parts IN the 2nd stage?
False. The pilot valve is a working part. However failure of the pilot valve would require abuse that would render any other regulator useless too. The Poseidon's are upstream valves which are their most interesting and significant difference from other 2nd stages. The 1st stage is a run-of-the-mill diaphragm.
*Do they actually breathe ANY better than, say, a decent Apek's or SP reg?
No. If you ask me the top of the line Aqualung is the best reg on the market at the moment. The Apeks despite being an excellent reg doesn't measure up to the Legend LX Supreme in terms of ease of breathing or dryness. The top of the line SP is also better than the Apeks in terms of work of breathing but SP's latest regs are more full of O-rings than the space-shuttle, which 'didn't appeal to me. YYMV,
