have fun building it! the mb6582 can be a good and even cheaper alternative - you need not fully load it, you don´t have multiple modules flying around and you can extend it...
Thanks Hawkeye. I already built an MB6582. I still need to house it though. I'm designing my own CS for it. I'm building the modular SID to really fully understand how all this stuff works. It's a lot of work, but at least I'm not gettin' stupider.
