Liquid pH test kits

[mark]

Currently using Hagen but not very impressed. Buddy was heading to Calgary so was going to get him to pick a Salifert kit up from Wai's (none in Edmonton) but they're sold out. Just to confuse me more, who ever I talked to at Wai's, said Seatest was a better kit.

Looking for comments / ratings of pH marine test kits (got to figure out how the poll feature works).
