I like the look of Vishay RCH series or similar (Tyco do an 
equivalent). The 50W version is rated at 5.5W without heatsink and 
is specified to handle 2500Vrms (that's 3500V peak) short term 
overload. If you want to bolt it to a panel for heatsinking, the 
insulation is rated for 3500Vrms (5kV peak).
