Well thanks for all the information it's very appreciated,
I guess my budget is around £100, I can guess a lot of you will sit back and laugh, and I can understand why, I know it's a case of you get what you pay for with this type of equipment.
You should get in contact with a local ham radio operator or club and put out feelers for a used scope. You didn't mention what your interests are and that is a factor. For example if your interests are in audio you can get by with a low end scope. However long term you are likely better off getting at least a 100MHz scope. New scopes are completely out of your price range.
Some of the cheaper USB scopes might actually be completely serviceable in the audio domain. However they likely will have troubles with almost anything digital.
One of the main reasons for the purchase is so I can check pwm for any noise, and this will help in cleaning it up.
That still isn't much help. Tell us what the PWM is for and how fast it runs.
I have tried looking on Facebook in my area (Cambridgeshire) but sadly at the moment the closest I can find is like 50 miles away, iv already been pulled a few times already, one when going shopping and another when I took my son for a drive as it helps him with meltdowns.
So? The shut downs do very little to stop the transfer of COVID. We can see this in China which went to extremes and still had huge problems with the infection.
I am thinking of trying to put off buying one at the moment and hope something might pop up but as I'm sure you all know nothing ever turns up until it's to late
I've tried to obtain a variety of tools over the years, via online sites and nothing is ever there until after I buy the new device. Buying used when the item is not mainstream is a struggle. You will have more luck getting involved in online auctions such as those offered by DoveBid and others that closeout businesses.
The smartest move might be to put off buying, find some part time work, overtime or whatever and build up some cash. Sometimes you are better off letting things drag, contemplate what you need and want, to do and then make your move.
I've googled and YouTube the scope and from what I can tell it's not to bad a scope they've put a lot of time into the software from what I can tell, it's also open source they offer open source module pcb.
Again that's for the advice, but for now the hunt goes on
Just trying to find best bang for the buck
Buying a USB scope is not completely bad idea. If 5 years from now you want to buy a real scope you can and keep the USB unit as a portable solution. The tech is certainly getting better and frankly I can see some really nice ones coming once USB-C stabilizes. You need to realize that most of the low end USB scopes are more like data acquisition units with limited voltage input ranges and lacking a lot of features. More realistic USB scopes do cost far more.
