Interesting name and quite a funny thread!
On the one hand reseller domainers would love it as it is LLL.co.uk , however as they are resellers etc they would probably pay upto £2000 for it.
On the other hand end users would want it , L* L* Limited , which brings it in line with a 'normal' three letter of that nature eg. TCL above.
The triple L angle could be taken further, aquire triplel.co.uk 3L.co.uk etc. and a ready made brand for someone to buy.
Personally if I was buying I would probably go to about £1.5k tops as it is a nice looking combo and would suit my 'LLL' names, however as above when it comes to end user I would place as above.
