I have tried Spiral Path and Landcaster. They were good, but came in boxes from PA, I couldn't choose what I want easily.
I swapped to CSA from The Farm at Our House 2 years ago, totally loving it. They farm right in Brookeville/Olney area. They do it market style means you can come, see and pick what you want. The farmers are young and friendly, I learned a lot from them about what to do with the produce, and some garden tips. They also have flexibility to make up your missed weeks. Highly recommend.
