I barely know how to use one, so I don't want to spend a ton, but I would like to learn to use one and it may come in handy in some TV repairs. I have noticed the USB versions are much cheaper than a table top unit but I am worried they may be inferior. Are there specs I should be looking for in a unit? I don't want to buy something that is not sensitive enough or just not worthy of the job. I also know that the probes make a difference, but that's as much as I know. What probes should I be looking for?

Don't bother, they ARE inferior and slow... with bandwidth of about 5-10 Mhz compared to 50-60 Mhz for the cheapest desktop ones. -

Thanks, that is what I figured. I will search for a nice used one.Comment

Even a 50 MHz analogue scope will be more useful than a crusty USB scope.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search.Comment

The sampling rate is often specified for only one channel.
Also take into account operating system support (especially 64-bit) - a scope with a USB port for recording (and for some models, adding brief notes) is a good feature.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment
