Both Parks and Pinetree have been good but there's also "Renee's Garden" - she started Shepherd's and sold out but couldn't evidently get out of it entirely. Now she has a small line out- good seeds, both flower and vegetable, and best of all - the veggies TASTE good, not just the largest, reddest, etc. There is a website, I think it's just reneesgarden.com but you can probably find it with Google.
Also like a lot Jardin du Gourmet out of St. Johnsbury Vermont - the 30 cent seed packet people. They send a very few seeds of some - but then who needs more than a half-dozen of angelica? They also have a nice variety of herbs and give some idea of uses (culinary/medicinal/dye). Nicest part is they're affordable if you just want to try a LITTLE bit of something to see if it'll grow at all in your area.
As for "running rampant" chervil and chamomile have taken over about half the garden, but I discovered chervil works quite well in flower arrangements too so that will probably be taken care of shortly! Chamomile tea from "fresh" stuff (flower centers only) is a treat not to be missed, but patience is required (a quart jar full is about 2-3 bushels and several hours of TV away.)
