I'm with Okuma.
Why would you spend top dollar on your camera's housing and then go and
quibble about money when it comes to the ONLY thing keeping you alive u/w ?
There are plenty of good s/h regs for sale around web sites, etc.. Buy a good
brand name and have it service by a good technician and then you can relax
while taking your pics instead of wondering if your "cheaper than $300 reg" is
going to give you another breath of air, or give up the ghost completely...
