MPD - The items you are selling in your webstore would eventually come up, your unique domain should come up as well in the searches. Search engine spyders will eventually find your store, and the more you refresh you content and the more traffic you draw, the higher up your rankings will be (scored that info in a recent understanding search engines seminar)
I agree that it would be far more logical to create your own eccomerce website. You can always link to your eBay auction from there. Yes the templated eBay store will save you money up front (my 1st fully automated eccomerce site cost $2000 USD + a $2000 security deposit to my bank for their payment gate way services). The credit card fees for me are 1.8%, monthly fees for all around hosting, merchant accounts, etc...are about $65 CAD, plus the site is much more professional looking than some template and you have a lot more freedom outside of eBay listing policies and boundaries.
Nowadays you can integrate PayPal with your website and use a number of other means to avoid the security deposit.
So you do the math - eBay's 1.5% + merchant fees + $250 a month, plus creative restrictions vs My one time start up cost of $2000 (much less for many others) + $20-65/mo hosting and merchant service fees) + 1.9% Credit Card fee (less for high volume sellers)
The independant route would definatly pay off in the long run.
