Well if current Sony low end players are no good mechanically in the long run, then don't bother. My only long term experience with an entry level Sony was the old 300 model. That was their first entry level model introduced in 1997 at $500. It's held up fine, though it's easily bested by any current player...
Maybe you should just pick up a
Pioneer DV-363-K (US model, $149 US list price)

Or if you don't care to import one, get the Canadian model
Pioneer DV-353-K(or-S) $199 list Canadian.
