I have a similar 6 x 4 and they are probably some the most common saws available . I too used mine a lot in the vertical with a small table added on to the guide. great for cutting bar but I found it limited when cutting sheets as anything wider than about 90mm wouldnt go "through "
I found a Sealey "Woodworker" bandsaw which does about 350mm for a princely £160 but then could not find blades 2350 long.
You can get them made though for not a lot.
