Please don’t pay much attention to the price of good in China. BTW, there are a standard, which you buy a better thing or the goods which just meet your need. In the future you can dispose the bad one or keep the good one, however you will so boring to put away the ji lei.
As to the electronic dictionary, which you really need, although you don’t need the function of pronunciation, you should need a better one because the more the function of dic, the more word in the dic.
For example, my dic is wen qu xin PC505, in fact there are no bid gap between the price.

是有点耗点，但如果不在上面玩游戏，一个电池用3，4个月还是没问题。好就好在体积小，随便哪个口袋一装，方便的很；词汇量够大，只要不是专业词汇，几乎没有查不到的。置于发音，我觉得不要也罢。

今天上午才买了深圳产的“大学士--卡霸”感觉不错，各大词典都包含。
价钱也比较好。只要￥480，与CC800比起来优点比较多。并且有楼上
那位兄弟所说的“金山词霸”，词典包含“郎文”、“牛津”、“新英
汉”等各大词典，另外需要“英英”、“成语”、“唐诗宋词”、“电
信专业”、“计算机专业”等SIM卡的按每卡￥78。现在LP正在摆弄，
感觉不错。就是电池为纽扣3V，不过为了以防万一，还是买了6块随身
携带。

不过只有英汉双解(即Longman当代高级词典)，无汉英字典。 RMB1000。7号电池。
