I have the promount 18 from woodbridge and must say it's been really good to me since buying in october last year,
If you are near them then it would be sensible to buy from the nearest supplier, when i have been there in person they have been really helpful, but service over the phone has been difficult, a bit of laxness on their part me thinks.
I am nearly 200 miles away so it's my problem really, but if you can just drive in and see them then it's got to be a bonus.
cheers
