I have a pair of Ikelite DS-125s with a dual TTL sync cord I've been shooting with for probably 9 years. They have been glitchy for the past year, and I feel like I am constantly troubleshooting them. Much of the time, one strobe fires and the other doesn't. Sometimes both fire. Just looking for opinions on whether I should send them in to Ikelite for service (not sure how much that would end up costing) or if it makes more sense to just upgrade to the DS-160?
Thanks for your input!
