Weller WESD51 is just as good if not better.
This would be it's most direct competition IMHO, and based on US pricing, both are competitively priced vs. one another.
But why bother when same money buys you induction heated XYtronic LF-3000/Quick 203h which is in another league altogether?
Not tried these, but induction definitely wouldn't be in the same league as either the WES/D51 or FX-888D from a technology POV. Better comparison would be Metcal, Thermaltronics, or the Hakko FX-100.
No idea on performance of the Quick or Xytronics, so I can't comment there. Would be nice to see it first hand though, as would tip quality.

If they compare well to the real thing, but don't cost near the same, they'd end up being exceptional deals.
... when you can buy $140 FX951 equivalent from quick, xytronix or even atten?
You wouldn't get a genuine Hakko FX-951 for that (~$267 here in the US).
As per performance, again, that's something that would have to be compared to the real thing.

Tip quality too.
For disclosure, I own the following at home:- Weller WD1 control unit, WSP80 iron, WMP iron, WDH10T Stop & Go stand, and WDH10 stand (no switch).
- Quick 861DW for hot air rework (110V version of the 861DS).
- Tenma 21-10135 hot air preheater (not identical, but a cheap copy of a Hakko FR-820).
No genuine Hakko whatsoever.
I only own cheap crap because Im cheap

But If I was going to buy induction heated station I would go for the ones I mentioned earlier, whole set at WP80 handle price.[/quote]
I'm cheap too, but I don't want garbage either (false economy situation).
Wasn't aware of Quick at the time I purchased the irons, and not sure I'd have gambled on it if I was. The FX-951 wasn't out at the time, and I got a decent deal on the WD1001 I started with (added everything else over time).
Regarding the hot air rework station,
wrapper posted about his 861DS as well as photos of the internals. We also exchanged PM's on the subject, and his information definitely helped to swing me in the direction of Quick, as Hakko, JBC, and so on, were too expensive. Saw a couple of used units I ended up passing on, only after having checked the cost of replacement parts (Pace in particular).
