is there any other opensource office software besides open office?  

You didn't say what operating system you are using, so I will assume that you are using a variety of Windows.

If all you need is a word-processor you could try AbiWord: http://www.abisource.com/

An alternative would be to use web based office software.

Microsoft Office Live is available for free use at the moment at http://www.officelive.com/default.aspx

You may also want to consider Google Docs: http://docs.google.com

I assume you have Windows if I am wrong and you use OSX I'll recommend NeoOffice, its based on OO.org and if you're running Linux I must ask why you didn't get OO.org in standard installation :P

Otherwise there's always Google Docs which work just fine and Lotus Symphony :)

Far the best way is to buy a computer magazine with a cover DVD full of software. If you check out what is on the disc before you buy you will often see Star Office or Open Office included.

try google docs
