Serious consider if its worth spending the money on the correct gear if you are only sleeving a personal rig.
For good quality pins, terminals, crimping tool, wire stripper, soldering iron, pliers, depinning tool, heat gun, you are looking at 200-250 GBP easy, plus the cost of shrink and sleeving on top.
Not wanting to sound like a ******** but its my honest opinion.
