Since you state that you can't solder (though you could learn :) ) and feels the sammichSID build guide is too difficult to follow (language wise).
Then you're kind of stuck in regard to the DIY projects unless you get someone to build one for you or find an approved sale of a finished kit.
I'm not sure how that works from the license perspective if you want someone to build one for you.
You could look at the HardSID product or find a used Elektron SIDStation.
The latter is not manufactured anymore so you'll need to look for a used one, pretty pricy, about $500-650 is what I've seen them go for when they pop up.
