yeah but that's a short term solution in my eyes, load of peeps who go for the swap-disk solution end up upgrading to a soldered chip solution because of the hassle (and in the past - unreliability).
anyway if you can't solder its not a problem 'cos there are chipper's around that will do it for you (obviously for a modest fee

)
save a bit harder then get an M2 installed, you won't regret it
