My parents had a pot with a top, and a crank in the handle that could be turned to stop the kernels from sticking. I suppose it's the more commercial version of what you grew up doing. It looks like they're still available for $20 or $30.
I've been roasting coffee stovetop for about a year. Takes me about 10 minutes to roast 12 ounces, the result is great, and it only ends up costing about $1/lb more than what I used to pay for roasted beans at Costco. If you like coffee at all, I highly recommend giving it a try!
The brand we've always had is Whirlypop.
