If you need a reflow oven, that's a different thing altogether, and you should probably repurpose an old toaster oven.
I delivered production boards (small run) that looked and worked great using a non-adjustable $10 30w iron (interchangeble tips, though) and a desklamp with the builtin magnifying glass.
You can't really tell the difference between a cheap setup and the expensive solder station I used in a previous employment.
They also contain a 120mm fans, a carbon filter and NO way to lead the fumes out oft the window.
However, you may be right that professional tools are the better choice in this case
I rarely desolder, but I can easily justify a hundred bucks if I can avoid all that hours of work, where I'm also risking damaging an IC, lifting a pad, or something else...
Small, silent and reliable for cheap money.
I did some minor mods and use these de-makeup cotton pads because they are cheaper but so far a great experience.
Another important note: don't go cheaper here. These manual desoldering pumps (<30 bucks) are pretty bad and the other zd-... Arent worth the money.
They even come with these compatibility wikis of what PSU or bank to buy.
