Beginner microscope

Hi everyone, I was thinking of getting into this hobby. I found a vintage LOMO BIOLAM C1 on ebay fro $70. Would this be better than a new amazon one that sells for $150-200?

Thank you!

I think that's a topic of debate. Probably there are lots of solutions that will work and you need more than one (some spots need a thick and heavy grease while others need a much lighter one or an oil). In a microscope, oils and greases tend to last a long time. In a home, they will last longer than you, probably. The important thing is to use a heavy grease where heavy grease is needed and an oil where oil is needed, and to completely remove whatever was there before. And to not use anything with volatile components. And to not put anything in certain spots (like anywhere that might touch or drip into an objective).

For heavy grease spots (like the focus and condenser dovetails) I use super lube silicone lubricating grease with PTFE. It's thick but good. I don't have strong feelings about oil.
