You can get a decent bench type pH meter for around 60 bucks. Worth in IMO.I agree, worth it but where can you find one for that price? Remember, they have to ship to Canada, the duty can't be too much and the exchange needs to be close to make it worthwhile. See, that's my problem. I can find all kinds of great stuff on-line but most of it doesn't ship out of the US.
I also need a new flask for starters having broken my 1 gal jug, a stir plate would be great. Some smaller flasks for stepping up starters, bottles for storing yeast slants, an autoclave, a large hadron collider and some other miscellaneous lab gear that I can't brew without.
