.... well, well, well. Slightly different, but a much closer fight. Lets see, i personally would narrow down the following :
1463J vs 3448J - i pick 3448J
1463ss vs 3448J - no doubt 1463ss
1463J vs 3448G - 3448G in a heart beat
1463R vs 3448J - 1463R
1463ss vs 3448G - thats a hard one, i pick 3448G
1463R vs 3448G - that my friend, i would take both.
all the above, we are talking about even steven condition, 88%+, should either model presents itself with original box and papers, we call that Happy worries. The little man inside of yourself will give you that answer.
