A kit is definitely a good starting point. One of the biggest hurdles with getting started in this field is sourcing parts. Having a kit, especially with a pre drilled enclosure takes all of that stuff out of the mix so you can focus on a successful build. After you've gotten through that, then you'll find that you can be a lot more adventurous. The AionFX kits are top notch and great places to start. I did one of those with my teenager that has gotten into guitar.
The Madbean boards are great and the docs are excellent with good info for sourcing the less common stuff.
