Buying a longboard

Hi, i was just wondering if you could give me some advice on buying a longboard. I have been surfing a fair amount and want to get my own board for surfing in UK and Europe and was wondering if youcould let me know what a good length and weight etc is good to go for? -i am 5'4" and want something taht is really easy to ride , light and, easy to paddle out on and duck dive with. I dont want a softop (i learned on those) and want something that will last me a while.
What good makes do you recommend and how much should i pay for a second-hand board?
sorry so many questions!
thank you for your help!
