Karl, I bought my rostrata from German eBay along with Ste and a few others so I reckon the seller your looking for Is 'Yucca-shop' they ship from Hungary I think it was, very quick delivery.
Not sure if he is still cheap but back then (2 yrs ago?) his stuff was a 3rd the price of everywhere else.
A lot of his stuff was bare rooted but last time I looked he had rooted stuff also.
Buying from german ebay.
