bike advise

[adam06]

hi, im panning on cycling from the UK to Italy and back. My current bike is a very heavy mountain bike which probably wouldnt do the job. I am also a poor student so want a cheap bike. was wondering if it would be a good idea to buy a second hand old school touring bike off ebay e.g. cgi.ebay.co.uk/CARLTON-CORSAIR-TOURING-BICYCLE_W0QQitemZ140319122713QQcmdZViewItemQQptZUK_Bikes_GL?hash=item140319122713&_trksid=p3286.c0.m14&_trkparms=72%3A1688|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50

any advise?

thanks
