I have been offered a "Nearly New" Sony Alpha A100 - and was wondering if it would be a good starter unit for me..

It seems tyo be heaving good reviews - http://www.kangareview.com/review/showitem/ITEMID/22745

but I wanted a few opinions from people that may know a bit more.. specificly, is it a good starter camera, and will i be able to buy kit for it and expand it, as i get better, and use it more etc...

cheers in advance
