I would urge caution. Do NOT rely on their website to reliably tell you if an item is in stock.
Being something of a news/radio buff we recently placed an order for a shortwave radio through QED-UK as they had the cheapest quote and were the only website in the UK I could find that had a particular model in stock. The website stated the stock levels were checked that morning, and 'In Stock'.
When placing the order, it asked for me to pick a delivery date, so I picked the next Tuesday.
Tuesday came and went with no delivery, email or contact or any kind from QED-UK, so we checked their website and it was listed as 'On order from supplier'. We emailed them to ask what was going on and they said it was on order and would take 10-14 days to arrive. We pointed out the website listed it as in stock at the time of order, and in fact STILL listed it as being in stock, and again stated the stock was last checked that same day. QED-UK advised there was an 'IT error' and they would report and fix it. The website STILL lists the item as 'In Stock' and ready for delivery.
I have also since then read other reviews from people stating their delivery times arent to be trusted and that their customer services is rathing lacking.
On the whole, I would say, good prices, but beware - the customer services leave a lot to be desired and the website stock check is unreliable.
Since my father used his card to pay for this order I haven't been able to check to see if they have charged for the order yet. Worryingly some reviews I've read stated that QED-UK charge upon order and not after dispatch. I do not know if they have changed their practices since those reviews, however.
Here is a link to some of the reviews I have found, some good some bad. You might want to take a look before placing an order:

Please let us know what you decide to do though and how it turns out if you do go for it?
