I can say the sliding doors on our 2011 CYV came from Romac, the same people that install most of the garage door openers in TV. I had Tim the Toolman Miller, the best handyman around putting security pins in my sliding doors. He got the drill hole a little too close to the glass and the entire glass on one side of the sliding door became a huge spider web.
Since Tim is an honorable guy, he didn't ask for me to chip in or anything. He said, it's my fault and I'll go get you a new door in the morning from the original seller and install it tomorrow, no charge. He went to Romac and the stationary side of the slider was $153. That was 8 years ago, but I thought was a good price. I remember in 1980 buying 5 sliding doors for a home I building in Pensacola and paid about $350 at that time. Romac is on Rolling Acres Rd and also in Leesburg.
If you want to see different sliders, go to Lowes or Home Depot, they have displays.
