Hey harpune!
Did you figure out where to buy your suit in Crete?
Anyway my advice is if you travel via Heraklion it would be a piece of cake to find a diving store there! There are also at least two in Ierapetra (I've been there 3 years ago but I don't remember the exact location, just that they were down town). Rethimno and Timbaki are also very likely to have diving shops.
Take care!
