I have been using Baker Creek for 3 years now. Nothing bad to say. They ship within 5 days, (I live in Ohio) and their seeds seem to always have a very high germination rate (high 90's). The only seed that had sub-par germination was my celery this year, which celery is finicky to begin anyways. Still germinated around 70%.
I think they are a good choice if your looking for unique varieties, heirlooms, or Non-GMO varieties. Also I really liked their customer service. Timely and understanding people.
I would say go for it! And to expect an overall good experience with them.
Hope this helps,
