Buying bare root orchids

[LavendarSunset]

OK, so now that I have officially become an orchid addict , I find that buying orchids 'locally' pretty much limits me to whatever is available at home improvement store nurseries (which is usually a small selection of Phals.) I have been researching online, and see that there are some nurseries that will ship orchids bare root.

Has anyone purchased and received bare root orchids? Is is a good idea to buy them this way? Is there a greater risk for disease and/or other problems?

Thanks for your input!!
