Sliders, if the operating hardware is suspect, can become hard to operate as well if you can't grasp the window sliding rail at a couple of points.
That alone is enough to convince me to stick with the casements. We're not going to want to have to grab a chair to open the window if there is an issue with the hardware. I can imagine the window always being operated by the bottom portion of the rail, which I think would lead to uneven wear.
One thing that nobody mentioned is that I'd be losing half my ventilation area since both casements open now but a slider would only open half the window. That's a big factor for the wife.
Cost...schmost...money is no object.
Thanks to all!
