That's analog for you.

More expensive? Yes, but compared to putting up with your VGA fuzzies, or buying more monitors and having somewhere to put them. No.
The issue you have of course, is while there are plenty of plain HDMI swtchers around, with remotes, being able to switch three monitors, along with the keyboard and mouse, is more complicated.
Many 2 into 1 USB+HDMI switched have a wired remote. If the remote connection is by 3.5mm plug, you can use a couple of earphone splitters and an F-F adapter to use one remote to control three switchers. Not cheap for three though. With three switchers though, you can possible switch other USB devices, though only v1.1 is usually catered for.
HDMI and DVI use EXACTLY the same protocol for video, so you can use HDMI-DVI adaptors, but you lose the HDMI's audio, if you were wanting it.
Attached is a connection schematic for the scenario I cite above:
I have shown the keyboard and mouse going into different switches, but they can go through the same one, or any of them.
