I love my dog. He's the best little dude.... and yes,
$1.
He brings me so much happiness, with his wiggly, playful, snuggly ways. I've always had and loved dogs, but I have especially bonded with this one like I haven't bonded with a dog since probably childhood.
As for care, it's not hard - take him out on a rough schedule/when he asks to go out and make sure he's got food and water. One of the reasons I got a small dog was so it would be easy to accommodate his exercise needs in our house/yard.
He mostly keeps his toys picked up and in his bed when he's not playing with them (we didn't teach him this), but he's tiny so it's not like they'd be huge tripping hazards anyway. The worst that happens is getting startled when I step on a random squeaky toy.
Speaking of being tiny, he learned quickly that I have no peripheral vision and that he shouldn't get under-foot.
Finding accidents in the house when we were potty training him was a little difficult for me at times, but the rest of the family was around to help out with that. I did most of the actual house training, though. After about two weeks of struggling with it due to the rest of the family not being consistent enough, I basically took a week off work and stayed with him 24/7 and kept super on top of his cues that he needed to go and made sure to take him out frequently. That's a huge up-front commitment and of course YMMV, but in our case, he learned so quickly that way that it was totally worth it (and I needed a break from work anyway).
