Small electronics vacuum recommendation wanted, please

[lafinfil]

I would reconsider using the compressed air in conjunction with a shopvac and a crevice attachment. Use the air to
displace the lint while using the shopvac to suck it out of the air while it is dislodged.

I use this technique for getting the dust out of electronics and photo equipment. A variety of soft sable hair brushes
used in the same manner to dislodge the lint and catch it in the vac,

I've also made reducers for the shop vac hose experimenting with caps (like from spray paint cans)
that were duct taped on the hose and a hole drilled to accommodate the size of tubing I need to get in a particular place.
