Yer I think go for the big kit. See, our wonderful stores over here liek to put a huge markup on the small ones, for AUD$20 for a small kit it was not worth it if buying 1 or 2 pills. And I payed AUD$50 for my big kit. But still 1 or 2 tests with brown liquid for $20 is no where near worth 200 tests with clear liquid for $50....so I say go the big kits...
