Not really worth it in my opinion.
It looks like a cute little tree, but how healthy is it? $60+ to find out. How reputable is the seller, and how well does he stand by his product? $60+ to find out.
Luckily, he says you can send it back to him if you arn't satisfied and he will refund your money, provided that you pay for shipping. So, in that sense, if you are dissatisfied with it, you spend $50 in shipping to get it to your door, $50+ in shipping to get it back to him, all to get your $1.60 (or whatever) back.
It's a gamble, and a gamble on $20 I'll take, $60 is better spent saved till you find a sweet tree in person (or from someone you trust).
