I tend to chop the thicker boards into more easily handled sizes such as 8x2 or 4x4 with a circ saw. The carrage on my Kity will only give me about 800mm of travel. And trying to lift a 25mm sheet at 60kg is not easy if working on your own, what are you making with that thickness, is usually use 18/19mm for carcases and 22mm for door styles & rails.
If you want it as a panel saw then look at waht axminsters list as panel saws not saw benches, it all comes down to how often you will need to be cutting large panels, if doing it day in, day out then a panel saw is the way to go. If its only one or two days a month then you can get round it.
