We places the order for a MEI EzFit NoBlock, but for the meantime we have to buy another edger (something cheap) to keep up with the work.

I have a good offer for Nidek/Santinelli LEX1000 Express. No tracer and no blocker.
The edger looks ok from the photos, but I will check it in person before buying. It has 130 000 jobs to date.

What should I check before buying?
How many jobs can such an edger do, if services regilarly?

Thanks for the help.
