Cost has not been an issue for me. I've got 14 tables on DynamoDB - most at 5 read, 5 write, and one at 20 read, 10 write - and its been costing me around $50-$60 per month. IMHO cheaper than running a MySQL database and a slave instances. It was great during development because I would create the tables in the morning, code all day and then delete the tables at the end of the day so I would only pay for 6-8 hours of provisioned throughput!
