Extremely easy to service snake, and parts are not too difficult to find for them.

Poseidon are great regs, but they can be a real pain to service. Parts are often difficult to attain and ridiculously expensive, plus there are the special tools required. I have heard of Poseidons going as long as 10 years (yes, regular use) without being serviced, but when the time comes it will make annual service on other makes look like a walk in the park.
