Small electronics vacuum recommendation wanted, please

[OWC Jamie]

I don't have a serger nor a sewing machine, but air in a can only has so much value.
I use a paint brush of an appropriate size and stiffness to brush out dust and goo from the inside of peecees with a regular vacumn nearby to suck up the mess.

I have used a dustbuster, but they don't have very good suction and the [rechargeble]batteries just do not seem to last.

If I think there's a possibility something might go up the hose of value I'll use a small shop vacuum and empty it out first.
