I made a best off for 65 and was accepted.. try 60 bucks and maybe youll get it all for less than 70! The tips are legit too. Ive used a few and they are all great.
Like someone sais the iron heats up literally in 10 seconds. Its insane how awesome this soldering station is.
For the past 2-3 years Ive stuck with radio shack 45 watt irons and every few months I buy new tips or just replace the iron.. probably spent a good 60 bucks on these crappy irons
The 936 is sick. hands down
