Then people say, how much is a charger.......then when they find out they say its too much, flash anyway and risk bricking an ECU.
A high amperage PSU doesn't have to break the bank. Granted you wont get the fancy features of a dedicated PSU but you can get a steady and safe 13.5v for a safe flash.
I used this guide to build my own and it didn't cost anymore than £50. My PSU pictures and the guide is in the links.
