Does anyone regret doing fake flowers?

I don't have room in my budget for a florist and I'm not sure if I could recreate the look I want on my own because I'm doing a small amount of flowers as it is and any online wholesale option I've seen is going to be almost as expensive as having a florist do them for me. I'm considering either renting my bouquets through a site like Something Borrowed Blooms or trying to DIY them using silk flowers. Did anyone regret not splurging for real flowers on their day? It seems silly but for some reason I keep thinking there has to be a cheaper way to do flowers that I'm missing.
