Oscilloscope Help

[terry]

Hi, I am after some help, my old Oscilloscope will only work on Windows 98 and I am upgrading my test pc to XP Pro. Should I save my money and get the PicoScope 2203 or buy the PicoScope 2204, PicoScope 2205. The Bandwidth on the 2203 is 5 MHz, The 2204 is 10 MHz and the 2205 is 25 MHz.

I am only use this to fault finding LCD monitor and LCD tv.

Here is a link to the Oscilloscope
