Can anyone recommend some good ones? Has anyone heard of Speedway SD-175 or is it some crazy off brand? Thanks!

Marco LM-6E and the unsinkable B&L 70.
The B&L 70 can be brought back from the brink so if you have some time and patience you can get parts and restore it to working condition after buying it for a bargain.
The LM-6E is just an all-around good machine. It has a prism compensation ring, and its the last model that they used good materials on. Later models are made of a chinsy plastic that feel like you could break in half if you sneeze hard enough. Hope that was helpful.
Yes, thank you! That was super helpful! :)
Our Marco is considered our better lensometer. We have a 2nd one that is some no-name from China. The Marco is much better constructed and reads a higher range of power but the knock-off is actually more accurate. It is also considerably newer. I will not attempt to adjust the Marco- I just compensate the difference in my head.
The American Optical 603B lensometer and the B&l Model 70 are the best. They are heavy duty and will last a life-time. Look on ebay and you might find a used one.
I think there is a retainer to put in prisms for prism compensation. I'll look tomorrow at the office.
I have a Marco LM101 and it is a tank. Definitely no chinzy plastic pieces in this thing and I got it about 6 months ago. I love it. Super accurate.
Is the Topcon LM-25 a good lensmeter?
A B&L model 70 is the best in my opinion. 2nd best is the Marco LM - 101. However the B&L is the better choice.
