Hi Bazza
welcome to the forum. If you get a used hose it will be at least 17 years old and buying a new Yamaha one will cost more than a braided hose. Hel hoses are very good and give forum members a discount (25% I think)
As for the seized piston, have you tried clamping he free piston in place and pumping the pedal to see if that frees the seized one, it did with mine, it was slow but it moved. I didn't pop it all the way out I just smothered it red rubber grease and moved it in and out a few times to ease it a bit, I'll pop it out and sort it it properly when I replace the hose. Hope this helps
