Another thing to keep an eye on with Walter's orders (although I hear they've changed it up a bit recently) is the Elle paper pots that they use. Here's a thread on that:

I've only recently worked with liners a bit but I've made a solemn vow that whatever I purchase, whether liner or grown out a bit in a nursery, I will do my best to remove the soil from the roots and plant them bare root. That way, if there is any root crowding involved I'll be able to catch it. I lost a very nice little 'Lakeside Paisley Print' because I didn't take the time to inspect the roots. I have a feeling that if I'd soaked them and taken them down to bare root I wouldn't have had the problem that I did.
