90th way

Think building an ebay business is too much like building a normal business? If you've got the capital you can take the easy route. A lot of ebay "shop" (businesses) come up for sale in site-for-sale forums and with buisness brokers. The ebay username and feedback generally accompanies the business so you continue to benefit from accumulated goodwill (though the "transfer" is something that eBay may not approve of).
