Our local water temps are in the 50-70°F range. When I was diving wet, I would wear the 3mm Seasoft Dyna-hide gauntlet gloves. They held up well over time, but I found that I lost a fair amount of dexterity. Pushing little buttons on a camera rig is important to me, so this was a deal-breaker in my book.
I bought a pair of 5mm Henderson Hyperstretch Titanium gloves, which actually gave me better dexterity than my old Seasoft 3mm ones. They were also easy to put on and peel off. I needed to invert them to allow them to dry after post-dive rinsing, though. I ended up wearing the Hyperstretch gloves when I switched over to a drysuit. They worked OK for a while. Since I switched over to drygloves, my hands have been dry/warm even on the 80-90 minute dives that we do. I've noticed that finger dexterity is decidedly better in my drygloves vs. the Hyperstretch 5mm gloves.
I would recommend the Henderson Hyperstretch gloves. I have no idea whether there's a better, more economical option out there. The nice thing for me now is that the replacement cost of my drygloves is $4/pair. So far, I've put about 80 dives on this first pair...and they're still going strong.
Hope this info helps...
