Save your pennies and buy something 14".
The RS 250, ive had one for over 20 years is a fantastic little bandsaw, and will do rip,cut anything up to its scope size. But the capacity is really quite small, depth 120mm gives a range of operations, but you will find you are wishing for something bigger.
I, for a number of jobs can do away with the upper guide assembly, so i have and its gained me from the 120mm to 165mm depth of cut. Now if it wasnt needed i wouldnt have had to take those steps, and if I ever get a chance I'll replace the 250 with a 350.
But all in all the RP250 is a good small sized bandsaw. It is accurate even on long max depth ripping in hardwood. Cant say fairer than that.
