Just a little piece of advice here. Unless you already know someone that works for the manufacture or you have some insider information related to that you may want to reconsider getting into selling electronics. These are my reasons just so you know that I am just playing devil's advocate here.
1. Electronics niche on ebay is saturated right now. Every new person getting online and going straight to eBay thinks that they have found the best deal on the net when it comes to high end items...research it a little bit and you will understand what I am talking about.
2. Profit margins - In order to compete on eBay with the items that you are requesting you must buy in bulk and even if you do happen to find a wholesaler, you would have to buy in big lots because half of the eBayers that advertise on eBay get their big ticket items for literally pennies on the dollar.
Now solutions to the problems (at least in my mind as I am not familiar with your financial status, etc.) maybe consider doing the lower end items related to the electronics...I know that sounds really corny but think about it just for one second. Here is the scenerio:
You happen to find an item that you are able to sell on eBay for about $500.00 and it only cost you $350.00. Now you have to subtract the listing fees, the fees by your payment processor and you end up making about $55.00 (all of these numbers are hypothetical). Not to mention that you have only made one sale on that item.
#2. You get into power cord supplys, electronic accessories for ipods, mobiles, etc. ALL of these items can be extremely cheap if bought in lots and you could start less than $100.00 out of pocket expense. Markup can be very great and people will tend to try you out more if you are selling a cheaper product ($5 - 30) before they will buy from you at $100+ (well unless you have impecible feedback)
I hope that this helps a little bit or at least gives you some food for thought.
