Jeezuz, how expensive is that. I would keep an eye out for 2nd hand if you don't need one right now. I just sold my D22 hardlid (Nissan) for $440.00, perf cond, and the guy who bought it is getting it resprayed to his colour.
Of course it depends as I mentioned when you need one.
the honeycomb composite ones are best make sure they are vac infused for finish and weight(lighter) they are stiff and will take a bit? The ST and STX are slightly different tubs so be careful (corners and lengths different) Ive seen the autoremote lock versions $2400 or the twin manual locks around $1700 ,good value I thought and Aussy Made. trev
