I have an Edsyn ZD500dx desoldering station which i find is excellent for all types of board repairs.
It's the only station i've owned or used so i can't compare it to any other brand.
So far it has worked flawlessly and is simple and easy to clean......i love it!
Made in the USA

I did a lot of research before buying and in the end It was a toss-up between Hakko or the Edsyn
I decided on Edsyn after seeing a lot of non-working Hakko's for sale on ebay US with missing or damaged handpieces and that turned me off them.
I'm sure Hakko desoldering stations are good as well as a lot of people rave about them.

I have had a Hakko 936 iron for years ,never a problem with it and wouldn't trade it for anything.
