Hi, unfortunately the forum does not allow excel attachment. Anyway interested buyers can always create their own spreadsheet, analyse and compare which suit them better....just my 2cents.
The below score was derived first by marking the score(max 100) for each category, follow by modulating it against the percentage weightage for now and 10yrs later...Its kinda very personal opinion but i found it useful in making a decision...
