You can use leaded solder for home/personal use. I can't get on with lead free solder either, melting temps always seem to be too high and can never get it to flow like good old 60/40.
I believe RS components sell leaded solder like this;

Maybe worth trying eBay as well. Can't help with the tips I'm afraid as you don't say what iron you have, but Weller and Antex are always pretty good.
