I'm assuming you wpuld only use a compressor to test not as a final solution as the compressor would need to be running for an hour straight to draw a vacuum whilst you do the machining?
depends on your priorities. yes, i suggested to test it using the compressor which makes perfect hold down.

having in mind a compressor on a boot sale is 20-30euro or brand new is 70-80euro, who cares if it will last an year or 2. electricity price and noise are the only real life concerns. people have reported compressors running like that more than an year without any problem. as i said before this is much more easy for the compressor than to compress.
