That's part of the "beauty" of the SX-100 (90 and I think 80 as well), they have
disposable cardboard traps. The 100 series tips have also been redesigned.

The 808 is nice, I have one. They come up used on ebay from time to time

But I've been spoiled now.
If you have the bucks, go for a Pace station with an SX-100 desoldering tool.

Watch out with using compressed gas duster (*not* canned air) on anything

Another vote for the Hakko 472D. You can pick them up cheaply as used
equipment. Do note that if you prefer the gun style handle over the pencil
style, you can interchange them. If you have shop air, there's an even
cheaper Hakko 470B -- I've heard it's a better/more effective pump than the
472D's
