Best buy, A scaffolding plank... we have heavy clay soil which is unworkable dry but sticky and gooey (?) when wet. Lay the plank down and you can get at it without sinking up to your Knees! The best thing was it was free, we need to buy another after 13years it is starting to decompose, you can see through it in one part!
Worst buy, an extra long fork that was shorter than our original one, Draper bought off the internet... OH bought a stainless steel fork (Wilkinson sword) having finally broken the cheap wilco one after about ten years. It came with a lifetiome guarantee and she broke it in about five weeks! She is a compulsive digger but at under 8 stone she isn't hefty by anybodies standards!
;D
