I got a 'show deal' at last year's GTI International - £600 inc VAT for the cooler, hoses and other gubbins, and another £20 for spraying black. Maybe speak to Forge directly - either Russell or John, and ask them if they can do a deal. Butter them up saying how good their kit is, and how you know of others who got it for 600 notes . . . . and £700 is just too much, I might have to get the cheaper APR one . . .

Got nothing to loose, and Forge generally are extremely helpful - and the quality of their products are arguably the best you can get.
BTW, what is the current web price direct from Forge?
