The Growing Place has a fairly good selection with prices in the $25-30 range. I usually order from Roses Unlimited in South Carolina.

Thanks for the tip. Today I was out at the Sunday Antiques Market at the Sandwich fairgrounds. They say that sometimes you will find what you are looking for in unsuspecting places....and I did. There was a John Cabot rose, one that I had never seen before, so it came home with me. Nice color, almost wild looking. Still have space for a couple more.
