What are you guys using to solder stainless?
I have had decent success using some stay-clean flux and normal electronics solder, and if that doesn't cut it I use l3oertjie's method of wrapping some wire around the joint.
But as things get smaller and tighter it would be nice to be able to just solder things together.
These are the flux's I'm looking at, that seem to be popular. (the two LA-CO products may even be available locally

)
Rubyfluid Stainless Steel
LA-CO M-A
LA-CO N-3
Any recommendations for solder?
