I have been in the market for a new high quality soldering station for the last 5-6 months. I've done a great amount of reading since I have never owned a high quality soldering station, and don't have first hand experience. I only used 2-1 reworking chinese stations and some Hakko clones.
There are a few that are price-wise and quality-wise at the top of the market: JBC, Weller, Metcal, Ersa, Hakko, and a few others, but not quite as easy to procure as the ones mentioned. They are all high quality brands, and have quite a few models. Between them there are pros and cons, which basically come down to: tip price, handle size, thermal recovery, handle cable length and flexibility, unit price - given that sole unit will not break and give up on you.
JBC is best in my opinion, but do not trust it as much as others' who used some of those systems. JBC has best thermal recovery, great and fast sleep system, small and light handle(s), long and flexible handle cables, great looking unit. Out of all advantages I would emphasize
thermal recovery. On the other hand,
tips are quite expensive, but they claim they last long and with instant sleep mode they will last even longer.
You should also count in different regions. Some of these manufacturers are present and widely available in some regions, while they may not be in others. Also, prices vary a lot with regions, that's also one of the reasons why some are more popular in Europe, and others in USA.
There is also one geeky thing about JBC: 0-300c in 2 seconds
