My advice to you is to go down to a local wood yard that supplies timber, fencing and roofing materials as they will also supply the tools that the blokes in that line of work are using.
Over the last year I have had to replace the roof on my place of work. Whilst watching the 'chippies/roofers/etc' do the job, they use fantastic little power drill / screw drivers. These machines caught my eye. After batting on doing other jobs with my old cordless and trusty traditional Hitachi wired drill of 25yrs vintage, I knew it was time to up date, particular with regards to working in the field, knocking timber boxes together out of old pallets and such like. So I asked one of the lads at the wood yard. They have Bosch and other good brands, but I have ended up with a Millwaukee, I presume American badged, made I know not, but it is awesome. Very small, two small batteries that last, I mean last and helish powerfull, will send No 8 screws in to wood and build a box on a pallet on one battery. It also fits into my day sack. (Small ruck sack that goes everywhere with me, a good military skill).
It cost £150. I was in the garden centre purchasing seeds, 5 plastic seed trays ... £7.00 ?? I have knocked 2 biggens together out of old wood and ply in the time it would take me to earn £7.00.
"It's the man (person) with the tools that counts". My old man often sez!
Money is worthless, Bankers are ***$*?kers, purchase a good drill and keep it in your Day Sack / Hand Bag (delete as applicable ). You know it makes sense.
