Hello all. I'm looking to get a used studio lighting setup, mostly just for fun and family type photos. I've been playing around with off-camera speedlight for a while now and am having a lot of fun with it. I've been trolling craigslist and am finding some good deals on 2-4 light sets. One brand that keeps coming up is Balcar. Now, from doing some research these seem to be quality items but I'm wondering about the future availability of of flash tubes should one go out. I've seen a couple of online resources currently but am curious about the long term. Any thoughts would be apprectiated. Thanks. Mark.
