Buying an Oscilloscope for hobby use....?

[Conn]

i'm looking at purchasing an oscilloscope just for my own personal use to tinker around a bit. it's been a while since I've used one, (college) and didn't use on for very long when I used it...so I'm a little unfamiliar.

I'd like to not spend over $175 on one.

Can anyone that knows more about these provide some insight?

Any help appreciated!
