iPad Spreadsheet ??

I've searched for an ipad spreadsheet on this site, nothing much came up.  Apple's App store has quite a few, but none with good reviews. 

Apple's own ipad spreadsheet offering, called Numbers, has very mixed reviews.   Anyone here used that?

Others:Office2 HD and Quickoffice Pro HD cover Word and Powerpoint as well, so maybe not the best for a spreadsheet. 

Does anyone on Aweb have any advice on what spreadsheet worked well for them?

BTW the best app for my ipad has been LogMeIn Ignition.  That lets me run my office computer from anywhere that has an internet connection.  Takes a bit of getting used to though.  I spent 6 months on a boat this year going up to Scotland and back, and met all my fortnightly deadlines.  But it would be handy to have a decent spreadsheet ....
