There are people on the internet who use leaf blowers to clean their PCs and those who oppose them because of potential static, blowing components off, etc. Meanwhile DataVac and CompuCleaner are very liked and recommended by so many people. So, how are they different from regular leaf blowers? Are they safe from causing static electricity in the air?
 
Amazon.co.uk doesn't ship CompuCleaner to Bulgaria and Datavac can only be ordered from the US which means it will cost me extra taxes so I'm left with the only option to get a leaf blower but because of so many different opinions, I can't decide for myself, still.

I want to get the datavac but they don't ship to my country so I'm looking for an alternative and I'm trying to understand if there is a big difference in regards to dusting quality and safety. 
 
Please don't recommend me these huge compressors that cost 5 times the datavac and compucleaner. I'm not going to clean 100 PCs a day. 

Its a slap in the face is what it is.
