Ian,
Had same prob last Nov, got my part about 5 month later, well they dismantled a sprayer to give me my part as it was stuck in customs (note: bits I ordered from usa arrived at my home in 16 days, not 5 months). I have had to ring several times ever time I need something, or speak to someone.
Now I am not knocking Alltec, as I have used them from their 1st year of business and Robert Saunders is one of this industry greatest, having done more for more cc companies than any other supplier, (yes its not just about selling stuff), but in this last year something is not running smooth.
Shame cos they are a great company with a good staff.
