"One gives you absolutely zero ongoing customer support or legal backup. And the other is ebay."
The law gives you redress if its faulty so its irrelevant what a given shop provides in the way of consumer protection. Also ebay is full of scammers and junk. At least in a physical shop you can see what you're buying first and take it back the same day if it doesn't work instead of pissing about going down to the post office to send a parcel and hoping for a refund from some nameless person who might be a fraud (assuming you received the goods in the first place). Quite what the appeal of internet shopping - aka electronic mail order - is I've no idea. Mail order was crap 35 years ago when sending off a cheque to Sinclair and hoping something showed up, and its crap today.
