Need some help--ID phono needle and where to purchase replacement

Yep, start looking at photos and when the match comes up....there you are.

Then come back with the seeming match (link) and ask again.

Where we will confirm or deny.

But it does look like a sub $20 conical, for the most part.
Gonna need the brand and model of turntable as well, as it might be directly associated with the brand and model of turntable.

Another possible source is "turntable needles.com"

This is also a good place to find styli:

I bet if you sent LPGear your pics, they could tell you.  I've seen that cart before.  Looks like a cart that came with the table.  Could be made by several manufacturers.
