Soldering Iron Temperature Controller

After buying a crap soldering iron, I found that its not good enough to solder even the most basic of things. I have a $30 gift coupon in RobotShop thanks to jorgen and I thought of using it to buy a new iron for me. Ideally, I want to buy something like this but my budget is limited, so limited that I can't buy it. As a result, I have decided to buy this iron. Even though that comes with a replaceable tip (which is required by me), it doesn't have a temperature controller, not even a manual one. So I thought if you guys will be good enough to help me make a temperature controller. Any links that help are appreciated.



Searching on Google, I found 2 of these links as relavent-Instructables and Another site. How relevant are they to this iron is the question (Sorry, I don't have the iron in my hand to experiment with)...


Update-
Well , I've decided to buy this iron. The robotshop issue was solved pretty easily. I tried to claim the gift card jorgen had given me to buy the iron mentioned above but for some reason, I couldn't (it kept on saying that card not accepted) and then it struck me, if jorgen has to buy it for me, why can't he do it with his account and send it over to my address. We started discussing this yesterday and jorgen has agreed to buy it. Why this iron, well it's the only iron that suits all conditions- replaceable tip, temperature controlled and under $20...

I just said above that I can't buy that iron even though it'll have been an ideal choice. Atleast check the links! It costs me $54+ after shipping!! So even if I reduce the $30 jorgen has given me, I'll have to pay $24 which might just be the end of my robot making plans!! You know from shot box on how tight a budget I'm on!!

So it's around ~USD$ 37 just for shipping???

I know shipping can be somewhat expensive, but still... Considering the ~$17.5 station it's very similar to mine specwise, (only the shape of the station itself is different, and actually more compact) I would never expect SO MUCH from shipping price.

Well I understand that the voucher must be tied to robotshop.. still the optimal option would be to find a good local deal. Even if it's not at your doorstep within India there must be some e-shop (not necessarily robotics shop) that sells soldering irons that might just have a suitable one for sale? Also, that way the shipping costs wouldn't be so high? no?

As per your specific requirements, I know nothing about smd soldering (besides the little I know about the regular soldering) so I can't say nothing on the subject. However, it might not be a bad idea to search for like a niche of smd soldering freaks community or something like that :P they might be more suitable to help you with this specific issue.

Isn't there another vendor out there you could go to? Preferably someone who won't charge a fortune worth of shipping costs? I can't imagine you'll find a temp controlled one on such a constrained budget..

you can the soldering iron as you want here

I find 2 faults with that, both fatal-
  1. It'll also require me to build a temperature controller as I've got to do smd stuff. Even though it says that it holds the temperature, I don't know what temperature it'll be holding so say after 20 mins, it maintains 900° C, well, all of solder is going to vaporize at that temperature.
  2. At 25w, the iron is going to loose temperature pretty quickly. I don't know if it's relevant to smd but after all the comments I've read, it looks lik it'll be better if iron maintains temperature longer.

i have a 25 watt weller but you have to wait 10 mins for it to heet up i got it for $10 at coles and i like it becus its a good low heet its ic frendly 

Well, I need it to be temperature controlled with replaceable tip as while a normal iron is good enough for through hole work, I don't thing it'll he good enough for smd stuff...
It has replaceable tips and you can buy um with stations
