I bought an Atten ST-80 for about US$120 direct in China.
I like that you can set 3 temperatures and that when you manually change a temp it jumps by 5°C, so you don't have to press forever.
I also like that is has a sleep mode that you can program, if the handset ain't moving for the time you set it goes to 150°C
It uses standard Hakko #900 type solder tips, so you get cheap tips too (quality varies a lot though if you don't buy original Hakko)
Not so good: heat up time is about 30 Seconds.
I am considering a DIY iron with a Weller tip, that heat up in 3 Seconds, like this one:
