I am wanting to get a camera lens so anything I am not using regularly is being sold. This focuser is very very good. usb 2.0, very strong and I have never had flex even with heavy loads. It is extremely precise.
Bottom line - this is high quality equipment.
These were around $2000 new including shipping and GST I'll sell this one for $1000 including shipping.Its in good condition, perhaps a few minor marks but everything works perfectly:
