welding steel base or just getting aluminium extrusion

[cropwell]

Don't want to be insulting to anyone regarding price but personally i think this is disgusting but then i am no expert on whats worth what when it comes to stuff like this. i have been quoted just under £2k just for 4 pieces and 2 of those pieces are only small plates for the rails

I feel I have said this before, but Reefy, there may be two factors at work here :-
1. The company has enough on their order books to put them in a position where they can issue F**k Off quotes to one off machining.
2. They are cynically set up to cream off the desparate.

The price per unit if you were ordering 1000 off each would be a lot lot lower.

I would advise you to keep looking

Edit: Having looked at their website, I go for option 2.
