I'm not a veteran EEVBlog user and will probably be screamed at for this recommendation.
But I'm also trying to consider you price factor without recommending an iron that won't keep up with bigger jobs at 35W.
Also, I will admit I own a 738H for months without any issue, and have tested and used a 702A+ for a month, both of these have 70W irons. Don't quote me on this fact but I think some of the Hakko tips may also work with some Aoyue stuff, you may need to research that further about the tips.
Sorry, you will have to copy and paste the URL, the forum keeps reformatting it and the link does not work.
So considering your price factor but keeping it at a 70W iron have you looked at this one?

Or if that is still to much, maybe this one. This one was my first digital variable one from a few years back, but mine is made with the label Tenma. It's the same, different people put their name on it.
I did have some issues with big things, but expected impossible things like a big square 3mm thick aluminum heat bed for a 3D printer. But that was trying to solder wire onto a heat sink. They say it's 60W, I would give it 50W rating compared to my 70W Aoyue that recently soldered wires onto that same heat bed without an issue.
But if you stick to PCB boards and don't do big heat sinks this will work and is cheaper.

I hope you find something that works for you.
Ok, I'm done. Money some times is everything when you can't afford to do the hobby you love.
But start the yelling for those that want to berate me for my recommendations.
