I think it depends on how good the local instructors are. They're not as good as your old instructors, but if they're still significantly better than you - good enough for you to learn something from - I'd consider taking lessons from them.
I vote strongly against B: could cause you bad habits that later will cause you more $ and more time.
I will do C: good dancing is good dancing-- will still learn how to move more efficiently, isolation, musicality, etc.... than if you were not taking lessons.
or see how far you will have to travel to get good instruction... maybe something you can do on Saturdays..
I agree with Tanya. But only do C is you will enjoy the other styles. Remember your enjoyment of dancing is the top priority.
I have found some of the youtube videos to be wonderful training material. NOT TO REPLACE AN INSTRUCTOR..... But, if there is no instructor around or you want clarification, you can easily download videos off YouTube and play them back frame by frame to see what the pro is actually doing. It was a major eye opener to watch a lot of the top standard dancers this way. I found a ton of problems with my dancing this way and understand what it is I am doing incorrectly.
I agree with Fasc: C first, and failing that, a combination of A & D. In addition to good dancing being good dancing, you never know -- if you try a new style to accommodate a better pro, you might find yourself loving something you never knew you could love.
