My new ixus II camera is on its way to me , bought for £179.99. I wanted a decent small digital camera for when i go to hong kong. Just found a guy in hong kong that sells the following: Pentax Optio S4 HK$2850 (£199) Casio Exilim Z4 HK$2950 (£205) Canon IXUS 400 HK$3100 (£216) should i return the ixus II camera and buy one when im over there ? I wanted to get one before i go so i can get used to the camera and make sure it works ok ? what do you think ?
