Save up your pennies and get a larger model. That one is the 10"
For bandsaws its really about depth of cut and 135mm is not really that much(in bandsaw world) It's a very versatile bit of kit, for deep ripping, cutting veneers and the like, and you you do limit yourself at only 5"
I've a record power 10" B/saw of the same specs, and the 125mm is really no good, though that said it has lasted me a good number of years of home workshop use(although at the time i did also have access to larger 24" saws) but in home use it was ok, but i did find myself wishing I'd bought a bigger saw like the 14"
But even going up to a 12" saw, the depth of cut there is usually 200mm.
