Dark - LPS have already advertised the 2003 LCD for £599 inc VAT on these very forums (check the classified section). If you don't believe me about their prices - give them a call.
A retailer can cut that much money off because do you realise how much frikkin money WDP make off an IR3 at listed price!!! Now that is no bad thing as WDP do great things for the sport - but how the hell do you think they afford to sponser all those teams? They have to sell at an RRP (of sorts) to protect their margins, and rightly so.
Anyway, I am veering off topic...
Of course you can slap an Eblade on a standard cocker - but you are not surely saying that it will have the same performance as the Eclipsed Eblade Cocker? Or are you? Surely there is something beyond cosmetic enhancements to it? If not - hell, I'm ordering a bog standard cocker and e-blade!
