I had delayed buying a digital SLR until recently. I had to wait for the price/performance curve to get within site of my disposable cash. That finally happened when I found a factory refurbished Nikon D50 at Overstock.com.
The best thing about a DSLR is the instant feedback. You can quickly learn what effect each adjustment has on the image, decide what you like, and get the desired shot with limited guesswork. When shooting film, you had to log each shot and hope for the best. If it was print film, then the printing process was a key variable that for which you had no data.
If you’ve been on the fence, jump off. Buy a digital SLR and don’t look back.
