Try a non-Kroger/non-Safeway owned green grocer like Rainer Farmers Market, they generally have tastier veggies and fruit (along with stuff you don't get at chain stores) as that is all they deal in.
Limes are way cheaper at green grocers too, I swear its a Seattle thing where the large grocery stores know your only buying limes to go with your liquor, and thus charge obscene prices :c
I live in the valley and have been to a few of the fruit stands; Columbia City Farmer's Market can be OK too. Still, not much luck. I am aware tomatoes are hard as hell to grow consistently well and I should accept some variance, but man, outside of Red Roma Tomatoes (had had good luck with them generally for caprese salad), it's been tough.
Although I imagine if you can get decent vine ripened heirloom tomatoes where you are the msg would probably be unnecessary.
