There seems to be no cheap vacuum purger option around? I don't really want to put down anything more than $150 and really would much prefer spending 100 max.. I've been doing runs for ages but just heat purging really well. I keep getting lectured on how its a key process to vacuum purge but my runs are too small for me to feel that it's warranted to put the money down. I'll do 18g runs like once a month. Anyways, has anyone got any advice? Thanks.
