Little Gem , Little Gem MkII or the Ruby ?

[fortuosity]

Ok , wanting to do my first project since forgeting everything I knew about electronics "amnesia from motorcycle wreck" anyway I'm wanting to build a small guitar amp for my 9 yo daughter , Looking at the following ones ,Little Gem & Little Gem MkII or the ruby .I'm looking for opinions on the three from people who have built them as well as someone who wouldnt mind an e-mail or 2 of questions , an itemized parts list and description / explination of the part *such as*

1 - LM386 "audio amplifier "

of radioshack parts would be a big help also.

Thanks for any help
