content: Where are you located and what specs do you need? Is an analog scope or an older digital scope okay?I also have some HP logic-analyser/scopes but the scope part is fixed attenuation.

content: I *might* have a Tektronix 465 and a 475 I could be persuaded to let go of if you feel either would truly benefit you. You'd have to pay for shipping unfortunately.Please let me know by PM if you're intetested.

content: I'd look for someone willing to sell you a used TDS-220. It's all the scope you'll ever need if the goal is to learn electronics (and is the right size for your space, and is also digital). If you have an ambitious project in the future, you'll know exactly what gear you need.

content: Hantek is not a brand I have any experience with. I'd really look at a lot at reviews and compare the specs to maybe the lowest end Rigol scopes.It's going to be your only scope and you don't want to risk having something you might be disappointed with.Beyond meeting your minimum specs, I would say ease of use at this price range is the biggest factor. I have a really nice 200Mhz usb MSO that I almost never use because the software is so awful.If you're using an instrument every day, anything annoying about that instrument will just annoy you again and again every time you use it.I'm not saying the Hantek will be like this, but if you're going to buy an off-brand scope, you should make sure.Honestly, since you're just now learning, the absolute most important thing is your brain. I would try hard to find something cheap that will meet the minimum requirements for your school and personal projects, no matter how ugly it is.If you get into electronics more heavily, you'll want the extra money to buy components and books.I'd say a good book is worth much more than a shiny new piece of test equipment.Take your time here; I'm assuming your school has labs you can use, so you can afford to make a good purchase decision.Don't envy the friend or classmate who has shiny new things, years later you'll have the money to buy whatever you want and the knowledge to do more with it.If you change your mind about the footprint and your mind is set on digital, I do have some older digital Tek scopes like the 2440.I also have an HP54645A which is a bit smaller.I'm less likely to give these away for free.Another thing about used gear. If it's a decade or two old and still works, there's a good chance it will keep working (exceptions like components known to fail still on the board not-withstanding).I also recommend better-known brands because your instrument is less likely to be full of components running above spec (Rigol seems to do this) and less shortcuts taken, but it doesn't look like a gaurantee; for example, Agilent's bottom rung scopes don't even seem to be designed by Agilent (many suspect Rigol, or that both purchased the design from the same party).My last advice, don't buy an offbrand instrument without a personal endorsement from someone who has or has used one and has also used better equipment.Cheers[edit: typos]
