+1 on the none working partner and serious depression! I havent got a baby, but got a nice fat court case instead, so probably a similar cost.
Would love a polished plenum... think £100 is slightly too high though no...? Would have though £85 + P&P would be a fair price...
There is a lot of work that goes into polishing these mate, the £100 i quoted includes postage back to the buyer
