Commodities

I'd like to get exposure to commodities (partly as an inflation hedge) within an ISA wrapper.  I think I'd probably prefer a broad equity basket that included different miners globally over "direct" commodities investments, but if necessary that wouldn't put me off.  Similarly whilst I'd prefer to go a unit trust route, I wouldn't necessarily mind it being an ETF.

I do not want specific exposure to gold.

Does anybody have an ideas / suggestions?
