I'm new to this hobby and don't want to continue coming to the fish store every week to get my water tested, but I don't want to have to deal with looking at all of those colors. I have seen 2 digital test kits, the Hanna test kit and the idip, the Hanna test kit is very expensive and I've heard the idip is inaccurate. I'm not made of money but I don't want something that's too inaccurate. Wich should I get (unless you know of any other ones)?
