Nice one - been considering adding a 'scope to my kit for a while now. Biggest problem has been deciding what to go for and what to budget. No point dropping £1500 on a decent DSO that will be of no use in a couple of years as everything goes digital. At the same time can't bring myelf to spend £5k+ on a nice Tek with all the interfaces required to make it future proof and easy to use!
Be interested in hearing what uses you do come up with!
Ceenhad, with the right probes, software and soundcard you can easily turn a laptop into a reasonably functional oscilloscope as the line-in has fairly similar characteristics in the audio realm at least.
I vaguely remember how to set one up from my a-level physics days.
I did look into the PC based ones but they seemed to cater more for audio type signals, there are some USB oscilloscopes but they were more expensive and arguably not as good as buying a used one off ebay.
