I agree with the assessments of Santa Rosa and Bluestone, as well.
I get my bulbs from Brent and Becky's - brentandbeckysbulbs.com/ or from easytogrowbulbs.com. Brent and Becky's sells companion plants, too, and they have marvelous 50% of sales biannually, if you don't mind waiting until the end of the season to buy.
If you care to figure out the Yahoo site (which can be a little tough at first) you can get some really good deals through Pam (woodthrush) who does a *ton* of co-op buying. Much of what she deals in are starter or liner sized plants, but certainly not everything.
http://groups.yahoo.com/group/... (You have to have a Yahoo ID and Pam has to accept you into the group before you can view the goods.) Mamajack on Cubits does the same, although she does have a small surcharge.
