The cheapest way is to buy it on ebay...check for the seller's ratings. I know that if I buy it from ebay, it is more likely that it will be in stock, i might be wrong...but stores sometimes don't have it on stock. Word of advice, if you buy a lilliput, buy one that has touchscreen installed! Why? It is like 30-50 bucks more I think, don't remember, but it is word it.
