The EC pump claims 99.97% but costs 6 times as much! 99.5% is adequate for most jobs and I doubt that you could tell the difference if identical items were cured at 99.5 and 99.97% Having said that, I have no idea how reliable a £50 pump will be. My old EC pump would run 24/7 with no issues. If you do a lot of important stuff you have to decide if the one off saving is worth an expensive failure. The carbon in a large part can cost more than a £50 pump! However, I would have no problem with having one as a backup.

For a beginner making small stuff then a cheaper pump, those sold as air conditioning units for example, will be fine. If you decide composites aren't for you then you don't have an expensive pump gathering dust :-) However, if you decide to upgrade then you have a backup which is always advisable, IMO. Most stuff you buy comes from China, even if it says Made in Britain! (simply assembling parts imported from China qualifies for the 'Made in Britain' stamp) Not all Chinese stuff is cheap and nasty. My wife's Lenovo laptop, for example, is very good. Edited 4 Years Ago by Steve Broad
