No-I think the protection is pretty good on eBay and as long as you go with reputable sellers it can be quite useful.
My ebay rules.
Communicate with seller is a must.
Seller must have minimum 500 sales.
Seller must have minimum 100% positive feed back within first 500-1000 sales.
Seller must have no less the 99.98% positive feed back when having over 1000 sales period.
Always read carefully.
Following these rules never had a single bad experience with them and living in Ireland it's really really hard to pick stuff up without eBay Amazon.co.uk and a few other sellers are good-but for non brand new items eBay is the only option really.
