I've almost got my Crack done (my first DIY kit). I got caught by the 14U/15U slipup (I've ended up just clipping that wire and wiring it to 22, as in the original manual, since getting to 14/15 to desolder the cap was getting a bit tricky), but other than that, things have been wonderful! (Replacing parts I broke, great instruction manual & form, :-) ).
