If you can't get the plants you want from Lowcoaster (doubtful based on what you're looking for) then AquariumPlants.com is a good place to order from. I've personally ordered from them and my local fish club has ordered from them, both with sucess. The plants were well packaged and in good condition when they arrived. Others have been reporting issues with drygood orders from them, but as far as plants go I'd be willing to order from them again. The thing that I like about them over some other sites that might have slightly higher quality plants, is that they will actually give you a shipping quote on plants up front. No surprises.
That being said my next order is going to be from Lowcoaster. It'll be my first time ordering from him, but from the rave reviews he get's I'm sure that I won't be disappointed. So far his communication through emails has been excellant. If you don't want to order through AquaBid you can simply ask him for a plant list and order directly from him.
