In my opinion you would be better off buying (or in some cases drop shipping) new digital cameras. I find that people are very sceptical when it comes to refurbished electronics. I have listed both types as an test once and I found that people would go more for the new then the refurbished when it came to cameras. I actually listed both new and refurbished of the same make model and features at the same time with significantly different pricing and people bought the new item at the high price over the refurbished. Most consumers are very cautious especially when it comes to there hard earned money. Are you willing to offer a guarantee with them or set up some kind of service contract with a supplier? That also helps with the referbs.
