Greetings JCsumlin,
I have to agree with most that spring straps are very nice and really pretty easy to install. There are a lot of spring straps out there to choose from or you can make your own custom. If it is only the strap it shouldn't be to hard to adapt a new one. I would try a bigger Oceanic dealer if you know of one, use the contact manufacturer here on SB just to make sure Oceanic doesn't have a replacement strap that will work for you.
Just be sure to give the specific name and what fin. Pictures are always a plus for finding parts etc. I have obtained very good information from the mask,fins forum. You might wish to post there also. If you are have trouble finding what you need PM me and I will call my buddy who is a has sold Oceanic for a long time, he might have a set in his stock room. What ever you do borrow some fins and go diving till you get fixed up.
I actually would like to try the bungee strap method for an emergency strap repair. This is a good lesson to purchase extra straps and carry them with you. I believe that is why spring straps are very popular, I have never seen them break yet. Good luck and do not hesitate to contact me for information. CamG Keep diving....keep training....keep learning!
