For the conditions you describe I would go with an MK17 instead of MK25. MK25 will be finicky when it comes to diving with freezing surface conditions and will require extra care. Another alternative for me would be an Apeks XTX50.
I was never fond of Sherwoods. They are less expensive and bulletproof breath worse IMHO. SP or Apeks will have a better resale value too.
Aqualung is a great option too. You might want to check them out. They own Apeks and you can likely find them in the same place you find Apeks.
"less bulletproof"? Our 4 Sherwood Oases have been in constant service since 2000. I think each has over 1000 dives to its credit. I guess I consider that fairly bulletproof...
I never sell old equipment or buy used equipment; hence, I may not be sufficiently aware of resale value. Our old equipment is retired gracefully and, occasionally, provides nice memories: "Remember the time in the Bahamas when we ascended through a school of jelly fish in these shorties?????"

joewr: Apeks side vent feature? Sorry you've lost me.
Yes, both XTX versions have the option to use either a wide or narrow exhaust. I use the wide exhaust on my primary and narrow on backup. The 50, 100 and 200 usually come with both, the 20 and 40 usually only come with the narrow but you can buy the wide as a separate item.
Hi,
Please see my earlier post with a lovely photo of me diving Truk Lagoon with my long-since retired Nik V. The Sherwoods outlasted the camera by about 8 years...and they are still going strong. We used them for 3 weeks recently whilst diving off the Big Island of Hawaii.
Here is a URL that describes the Apex that I saw:
APEKS TX50
It is in German, but if you look at the second drawing, you will see the vent (nr. 15) that is identified in English as the " AP1677 Exhaust tee".
It may be that Apex no longer makes this model. I saw it once about two years ago on another diver's gear.
