content: Would anyone know where I could find one of these? I liked the look of it on David's Tear down, but the only 110v models I can find are on Alibaba with an MOQ of 20. If there is no source for these, would anyone recommend the Aoyue 474a++ vs csi 474a for through hole double sided pcb work?alibaba sourcehttp://www.alibaba.com/product-detail/Hot-selling-High-quality-Desoldering-Station_1664166023.html?spm=a2700.7724857.35.1.9Xzx2n&smToken=a3bbf441f2a349b2b358ca2c294c5750&smSign=Or0FpBdd3A48IUmQMDyB3g%3D%3D

content: You can search ZD985 on eBay and see what comes up. Memotronics recently stopped selling these units on Amazon and eBay, so currently I only see that one seller from Italy.

content: I saw the memotronics expired listings linked to in earlier threads, but that Italy vendor zd-985 is 220-240v only, he was very stingy on negotiations, and I would need to buy a step up transformer to run the thing, pushing me right up to $200. I don't know if running a 50hz device at 60hz matters, and at that point, I'd probably pick the csi or Aoyue instead.

content: I bought one of these seems to work well the company that sells it also has spare parts and a 1 yr warranty.http://www.amazon.com/gp/product/B00ABJ4AEC?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00http://www.sra-solder.com/

content: Last I checked, the Aoyue had inferior tips ...Anyway, the ZD-985 uses an 18V switching supply internally. I think it's a flyback design, so it *should* run off of 115V. Or it should at least be convertable. But even if it isn't, you could simply replace it with any 18V PSU. The only slightly tricky thing is that the PSU PCB also has the FET that switches the heater on it, so you'd have to wire up a small circuit, or use a relay.

content: If I'm new to electronics, and scared of messing too much with mains circuitry, should something like this be a usable workaround?http://www.amazon.com/Rockstone-Power-Voltage-Transformer-Converter/dp/B00CLY84YW/ref=sr_1_10?ie=UTF8&qid=1441819711&sr=8-10&keywords=step+up+transformerThe wattage rating of the transformer seems more than sufficient for powering the desoldering station, but I'm worried if 50hz vs 60hz will cause any problems.Thanks for all the help!

content: Of course, a step up transformer is the safest bet. Frequency isn't really an issue when going from 50Hz to 60Hz. Especially not with the ZD985, since it's got a switching PSU.
