I made my own subframes using flat black steel and a mixture of the original ones. Cost me nothing! The seat was bought off ebay for around £50 if my memory serves me correct. I think you can buy bespoke subframes but they are not cheap, best to enquire direct to the company concerned. Other than that go for the alloy or steel side mounted types but that will mean the superior bucket seat as well that use the sidemounts and not the standard underside mount.
