Implementing a system to detect transactions being confirmed is orders of magnitude more complicated than send and forget. I've sent literally tens of thousands of bitcoins transactions and have never once had a transaction that wasn't confirmed within 48 hours. The important part here is that I have always used the reference client with the latest ruleset for transaction fee calculation.
