I am interested in purchasing a housing and strobes for the Nikon D200 to be used primarily for cave photography in North Florida as a gift for my husband. He wants the Hugyfot housing, but I am confused when it comes to strobes. I am considering the Inon Z-240 or the Sea and Sea YS-250Pro TTL strobes. I like the size of the Inon strobes, but have heard that they may not have enough coverage. The Sea and Sea strobes have better coverage, but are bulkier. Any suggestions including other strobes to consider are much appreciated.
