If I were you, I'd check with localharvest.org or slowfood.com and see if you can find a CSA in your area that you can begin getting produce from instead.
You wouldn't be getting things like mangos or lemons, but in your region, you WOULD be getting pretty much any of the vegetables you like (within season - more greens early on, more corn/tomatoes at this point) - and it's quite possible that you'd also be getting locally grown fruit (plums, cherries, apples later, strawberries/blueberries even!).
The thing to remember about a CSA is that you're essentially buying a share of the grower's harvest. A well-established CSA should be relatively consistent in what produce they're able to provide; but things happen (drought, hail, etc.) which can impact how much is in your share. Last year was our CSA's first year, and two hail storms plus a grasshopper infestation impacted our shares a lot. This year, they have more hail cloth, and turkeys/chickens/guineas/covers to try to keep the grasshoppers under control more, so we are probably getting twice as much produce this year as last year.
It's not always beautiful - there are spots where a grass hopper got into a leaf, or whatever - but it's locally grown and organic and tastes divine.
Prices for a local CSA vary by region. Ours costs us a little less than $400 for 12-15 weeks of vegetables. We could pay less if we went out and helped them maintain their gardens, but my girls are still more likely to pull up the veggies than the weeds right now.
I have a post in TAO about what to do. All of my fruit was bruised, moldy tomatoes.. egh.
