They are still available used for about the same price on Amazon

They might not seem like a big deal, but having used those features for 10 years I would really miss them.1

Additionally, comparing this to my 15 year old model, the older model had the capability of manually entering CD names and artists so its search feature could be used on any CD

My only concer is that the unit can stand up to consistent use

More and more CDs support that now, and I've always burned CDRs using that feature, inputting the data (including track titles) when the original disc doesn't include it
