These have dropped in price recently.
For those of you looking to get yourself a non-sandforce SSD, your options are a bit limited (and usually pricey). These also give you a little more space than the 120Gb Sandforce drives too.
Samsung's 830 has its own controller and high quality chips :)
Notebook version also available here for the same price: http://www.amazon.co.uk/Samsung-2-5inch-Notebook-Accessory-Norton/dp/B005OK6VJU/ref=pd_sim_computers_1
Difference between them being one comes with a bracket for mounting and the other a usb -> sata converter.
