No experience. But you say "thinking" so...
You might want to just take the chance and try the Madell, then tell us how well it works.
You know the rest of this, since you were in the recent thread:

I recently went through the research on desoldering stations and started a thread. Ended up getting a Hakko 204 for my own reasons. Not many people here have a desoldering station. My guess is it's more popular with people that do a lot of repairs and mods, like hams, and isn't nearly as useful for builders.

It's hard to find a good station with built-in vacuum, even at higher prices. Everyone makes one, but most of them are limited in some way. The best of them want external air. If you're wary, there's a lot of good reviews on the internet for the Hakko 808. If you're more adventurous, you might try modding something with a fish tank type air pump or compressor. Or just get a high end soldering station and the desoldering attachment and use the pump or shop air.
Another route is to prowl on ebay. Yesterday a Hakko 2024 desoldering tool went for $21.70 (shipping included, although sold as-is) and today an FP-102 went for $89. You'd need to add a cardboard tube filter, an air pump with a fume filter, and some tips for both soldering and desoldering. Probably $150 plus the pump for a real nice setup.
