Nice one CP,
The "is it really worth the effort in developing mu own site" is one of the most popular questions I get to see, and it's always nice to hear from those that have taken that route.
Grace covered it quite well, eBay is a great way to get selling online. It's fast, simple and delivers you instant traffic. The long term goal of any online retailer should be to develop their own platform to sell from.
As you know, it is more work and certainly more expense in the short term, but the gains can even out quite quickly. It's all about traffic at the end of the day. Even though I always develop my own sites to sell from, I always keep a profile on eBay to ensure I am making the most of the extra traffic it produces ....... save me having to look to hard for it : )
Drop a link for everyone to check out your site when you're ready, may well give some others in the process, or considering the process of developing their own site some great ideas.
