First of all… travel regulators are smaller with usually smaller mouthpieces. For a lot of people, they are first choices for overall regulators.
Used regs can be a good deal. A scuba instructor offloading a recent high end reg set can save $$$. I got my Mk17/C370/R095 +SPG for $400 with a fresh service.
That having been said, look for recent models instead of ancient versions that you cannot get parts for. Also know what you are looking for- 55F water probably doesn’t need a cold water reg, but if you intend to dive deep an unbalanced reg will quickly affect your dive enjoyment.
