Amen to that, I would definitely opt for a gravity fed device, better efficiency, you can get into tight spots, etc. just one word of caution....reme,ber to put the cup lid back on....don't ask me how I know this.....regarding hoses, I found that any compressor supplier or art shop, are usually very helpful, I have a contraption that the owner of the compressor shop did for me to convert from the CO2 tank to the A470, with a couple of bucks.
