Total rip off, local stainless fabricators will make them for a lot lot less.
You need to decide what you want and wirte a spec, or better still, do the fab, cutting etc then get them welded up by any stainless welder, if youre not 100% certain get them tacked first. OK a bit of to-ing and fro-ing but a lot of savings to be had.
We made a set of underslungs for a 'stang for less than £200 (parts cost)
Its not that difficult.
I suppose it depends if you've got £2,000 plus burning a hole, amount of time you have available, and whether youre into making stuff or not.
