i just got a roll of solder from jarcar electronics 64 bucks cheapest roll 37 largest roll was $140 1kg , pretty much got ya by the balls if you want to buy local and have this as your hobby .
A while back being a keeper reuser penny pinching i used to collect the reheated solder from old boards while when scrapping parts and let it drop in a jar for future melting i think the way costs having gone up on this it may very well be time to start again collecting the conducting gold it seems to be these days !
