1 - mp3playerstore.com has had a horrible repoutation. Some have ordered from them with good results, but I wouldn't do business with them. Look them up on resellerratings.com.
2 - Innovatek products are low-quality, commonly known as "pieces of crap".
The combination of a vendor with known, documented issues and a brand that is known to have quality issues, I'd avoid it like the plague.
