Have two of FR-300 and three 808 (two died in last three years)
Hakko FR-300 works great. For around $300, in my opinion you can't buy anything that good. It is a Hakko 808 successor. Which in my opinion was average grade desoldering tool.
Fr-300 has easy to change tips with some improvements in tip design (coating and durability). Found that 1.3 mm works great for regular size eyelets, 0.8 and 1mm can be hard to work with, specially with 20 -30 year old circuit boards.
Suction power is better than older version, only downside is design of ceramic cartridge (seems loose inside the filter pipe).
I have set temperature to medium (right in the middle) and I am able to work with multilayer boards without any problems
Turn of when not using it, it saves tip as well as heating element.
In the past I have used various brands of desoldering tools from Pace, Weller and Denon, and FR-300 works better.
Hope this helps
