Just thought i would post my findings, after receiving the four film's back. I was pleased to note the difference in the service offered by the labs,return packaging,documents,freepost box/envelopes for next order from two of the four labs etc.

I found a clear favourite for my own personal use,this was Peak Imaging. I like the return packaging the unmounted slides are sent in,the freepost box is handy also. The most important thing is the processing quailty,of which i find Peak to be so consistent. The slides looked so clean and sharp,with well saturated color. The quick turnaround and resonable total price of 6.19 which was second cheapest,The Darkroom first just by a few pence.

I was pleased to note the quailty of all four labs tested,it is very encouraging to know there are a few good lab's still out there.
