I cant see how you could WIN here, if you dont have TIME then you dont have time.
The only way to sort it is a BLACK HOLE or TIME MACHINE, as both i am told from Movies will rip you apart lets put that out.
Without time it dosnt matting about Patience to Complete it.
£660 is a good Drive for me, if nothing is gotten out of it. it is £660 pee up the wall. And the only way to save it being wasted and flashed away is to WORK and FIND TIME. Bit shocked you got as far as you have done, not to just finished the last 10m of a long run, but its up to you at the end of the day. Can always pay another £1000-2000 maybe a lot more by the time you get around to it!
