DIN terminal block sleeves?

[Islandboy85]

I scavenged a bunch of DIN terminal blocks from some old equipment at work. I looked them up online, and it says they don't recommend using stranded wire in ten without crimping sleeves onto the wire ends. Anyone know of some sleeves that don't require a $300 crumpet or alternatively can be soldered into the wire?
