It's a competitive market out there and you're up against the Apple's of this world.
The price seems keen, but do some research first as to whether the players you are looking at are actually selling. Use the 'completed items' search on ebay to determine this.
Also look at ones that have actually sold and determine:
- Price (can you make the 5% or more on your selling)
- Features (are there any particular features that seem to encourage sales?)
- Ordering requirements. Chances are you will have to bulk order to make a reasonable profit. But then again, you don't want to be 'stuck' with unsold goods.
