You will get different opinions on both of these but I can say they both do a great job.
Just in case you don't know Craig I am a supplier of WFP equipment. Want a van mount? My advice is go with Gardiner. Excellent service.. advice ..prices etc. I have seen nothing but good said about them and I can tell you that their prices are very keen indeed. NO BS from them. Just good honest down to earth service and goods at the right price.
Just in case anyone might suspect this advice I have no ties at all or anything to gain from you dealing with Gardiner.
The only thing that I would add to any system if it isnt already fitted is a Varistream MK2 flow controller. Worth their weight in gold I reckon. Will allow you to control your flow very well and will protect your pump pressure switch from burning out whichever make you have.
Keep it simple Craig. You wont do any yourself any harm at all by dealing with Gardiner mate
