You should try it beside the 20" and see what difference it has.
Never played one of these but the bigger cymbals are sometimes surprisingly better than 20" for crashing. I have a 21 sweet ride and it's more crashable than any 20" iv'e played. Bottom line is you have to try for yourself.
If it's an A and as new, is looks cheaper than the the retail price so a good buy, but do you want the cymbal ???
