How much should i estimate the shipping to be on ebay?

i won an item yesterday on ebay and i am suppose to type in the shipping price. i dont know how much it would be and after emailing the seller 3 times, i still haven't received an answer. she lives in florida and i live in texas. the item is more like MANY items. it consists of a nice camera (the canon 20d, to ba exact) a tripod, a hard case camera bag, a flash, and many other little things. so i imagine it may be a little bulky and a little heavy. anyone have an idea?
