Can't seem to find much info on this scope and I'm wondering what one's worth. I know nothing about oscilloscope brands and I don't want to buy a piece of junk for my first scope
I guess you mean this one:

It's an old 100MHz modular analog scope with storage tube. There isn't much information around for this scope but it's at least 30 years old, and unless you're into collecting old and somewhat rare test instruments it's not worth spending any money on, especially not as the first scope for a beginner. Aside from the fact that as an analog scope its capabilities are extremely limited, simply because of its age it will also be close to the end of its service life. And finding a service manual and schematics will very likely be a challenge, which you'll need to fix it if it fails (aside from a second scope!). Plus, I'm not sure but I vaguely remember that these scopes contain some proprietary components which these days are essentially unobtainium.
In general, don't bother with an old analog boat anchors, unless it's free and works. These days very little money buys you a decent new digital scope, i.e. the Siglent SDS1072CML/CNL or the Rigol DS1054z.
