I like nice tools as much as the next guy, but the OP is asking about affordable options. I don't think he's working in a shop, so he's going to be using a cone wrench for a minute at a time, a few times a year. Not a big deal to use a uncomfortable one for that purpose, and easy enough to put on gloves, or just wrap a rag around the wrench.
I've also taken a cheap open ended wrench and ground it thin enough to fit.
