I know it's come up in the past that students/hobbiests have wanted to know how to test their design without an oscilloscope, and the answer is usually something like, "Bite the bullit or save up and buy an oscilloscope." This might be of some value to those guys.

It's bandwidth is only something like 3MHz, but it's only $199 for a DSO. What do y'all think?

I think that of "those guys" some will buy the toy and end up buying a capable scope (100MHz). Thry will forever regret trying to "save money". Even worse, someone might "believe the scope" and thus never accept that problem x is due to an unseen 10ns pulse coming in and thus never get the thingy debugged and go away forever frustrated.

For an expreienced person that will know what can be and what can not be seen, suuch a "toy scope" may have some value due to its pocketability.

another possibility: someone post "I have this problem" and every reply "what does your scope show" get the reply "normal". It will take umpteen posts before someone realize that the mentioned scope is a toy.
