Just be warned; I have (previously) found snapsort to be riddled with specification errors and make some pretty wacky statements*.
* Fine
if you know your stuff, but a seriously bad thing for anyone just starting out, or not well versed on the basics.
May also make a mockery of drawing comparison conclusions based on their 'data'.
Of course, there's a chance they have improved by now - but I doubt it, when I tried to alert them to an error, it was never corrected (before I gave up waiting).
Of the two sites mentioned above, I'd (personally) trust DPR more.
That said;
any such site is liable to make errors when inputting manufacturer's specs in to their 'database' (which may be no more than a spreadsheet in which they copied an existing entry and incompletely updated it when a new model comes out). This applies to store sites as well, of course.
Mind you, even manufacturers have been known to make mistakes.
Take it from someone that's spent time updating similar data sets and although I'm more careful than anyone else I know, I
still I find odd errors that I must have made. No-one is infallible, but some don't even bother to check what they put in, or better still; ask someone else to sanity check it. Nor even bother to correct it when advised of an error.
FWIW, Dave
